As you can see i have gone completely my own way to make this oscillator, it uses a 25KHz xtal and a 2n3904 transistor, 1M ohm pot and one 5k pot, the power supply comes from 15Vscaled down to 9V using 100k pot + 2n3904 + 1k resistor, i know the picture shows 10k but that didn't give me full voltage range so use 100k instead. I have no idea how it got this working and i am somewhat suprised that 2n3904 can oscillate at 20MHz+. submitted by /u/Whyjustwhydothat [link] [comments]

I love Design Ideas (DIs) with a backstory.  Recently, frequent DI contributor Jayapal Ramalingam published an engaging tale of engineering ingenuity coping with a design feature requirement added unexpectedly and very (very!) late in product development: “Using a single MCU port pin to drive a multi-digit display.”

Jayapal writes, “Imagine a situation where you have only one port line left out, and you are suddenly required to add a four-digit display.”

Yikes!  Add a looming delivery deadline to build suspense, and this becomes a classic nightmare scenario. It could easily develop, from an engineering standpoint, into a horror story straight out of the pages of Stephen King. Well, okay. Almost.

Wow the engineering world with your unique design: Design Ideas Submission Guide

But in a clever plot twist, engineer Jayapal shows how a bit (no pun!) of ingenuity turns this tale of terror into an opportunity for some cool circuit design. In his DI, different durations of software-generated pulses on that lonely port line become the control signals necessary for running the newly needed decimal display.

Crisis and calamity averted.

So I wondered how the same basic plot could make a basis for a more generalized storyline. In this version, not just four digits of numerical binary-coded decimal (BCD), but N bits of arbitrary parallel binary outputs would be driven in a similar solitary serial fashion. And all this would be achieved by the same singleton GPIO port bit. Figure 1 shows how the story takes shape.

Figure 1 A lonely GPIO bit loads a lengthy serial string of parallel registers. 

Incoming pulses of variable length on GPIO are buffered by noninverting gate U1a and drive three sets of inputs. 

1. Timing circuits U1b (400us R1C3 SER input zero/one discriminator),
2. U1cd (2.4ms R4C2 parallel RCLK clock AC coupled Schmidt trigger),
3. SRCLK shift registers serial clock.

As illustrated in Figure 2, the interpulse (idle) state of the GPIO is high = 1. 

Figure 2 GPIO pulse timing.

A serial bit transfer pulse starts when the GPIO goes low = 0, releasing the timing RCs. Whether the pulse shifts to a 0 or 1 bit depends on its duration.  If < 100 μs (T0), the R1C3 timeconstant will still hold SER low when the rising edge of SRCLK clocks the serial registers. This will cause a 0 bit to be shifted in. If > 400 μs (T1), the opposite will occur, and the shift register gets a one.

In this way, a data rate between 2 kbps and 10 kbps (depending on the relative frequencies of ones and zeros) can be maintained as long as the idle period between pulses remains less than 600 μs. Completion of data transfer is signaled by allowing GPIO to remain idle for > TR = 3.5 ms.  This allows R4C2 to time out and a transfer pulse to occur on RCLK, commanding a broadside parallel data transfer from the shift registers to the parallel output bits.

Note that, going back to the original horror story, four BCD digits = 16 bits, two 8-bit shift registers, and 12 ms would be enough logic and time. I think that makes for a pretty good ending for a yarn about a far stretch of a single bit.

Stephen Woodward‘s relationship with EDN’s DI column goes back quite a long way. Over 200 submissions have been accepted since his first contribution back in 1974.  They have included best Design Idea of the year in 1974 and 2001.

In electric vehicle (EV) designs, the shift from 400-V to 800-V battery systems is now a pressing issue. So, the panel discussion on the first day of Automotive Tech Forum 2026 was a good venue for a reality check on the future of 800-V EV architectures.

The panel titled “Powering the Electric Vehicle: From Semiconductors to Systems” explored the latest in battery management system (BMS) designs and what battery modeling tells us about the design challenges as we move toward 800-V systems. And how design building blocks like motor control in EV traction are coping with this transition.

The panelists discussed how 800-V EV architectures could reshape vehicle power distribution. Jerry Shi, sector general manager for EV, HEV, and Powertrain at Texas Instruments, spoke about the emerging 800-V EV design landscape, specifically from a drivetrain standpoint. He also outlined critical design challenges and viable solutions in this design arena.

Carsten Himmele, marketing manager for Automotive at Allegro MicroSystems, cautioned about the industry-wide adoption of 800-V battery systems. “The 400-V battery systems will still dominate mainstream markets due to cost and complexity trade-offs.”

Rohan Samsi, VP of GaN Business Division at Renesas, echoed similar sentiments while envisioning a deeper adoption of 800-V architectures to address range anxiety and efficiency concerns. He acknowledged the challenges such as cost, complexity, and consumer preferences. “The trade-offs between 400-V and 800-V architectures relate to component complexity and service warranty costs.”

So, in the 400-V to 800-V transition, there was a consensus that 800-V systems offer advantages in fast charging and reduced weight. However, for now, panelists expect that 400-V systems will remain dominant in mainstream markets due to their affordability.

It’s well known that the main job of a pulse width modulator’s filter is to limit the maximum peak-to-peak amplitude of the fPWM Hz-induced ripple. It attenuates this to a specified fraction—Frac of the full-scale PWM output—while passing PWMavg, the average value of the PWM signal.

Wow the engineering world with your unique design: Design Ideas Submission Guide

Although the duty cycle can change instantaneously, the filter’s response to that change takes time to settle. It’s convenient to define the settling time Tfrac to be that after which the transient response remains within ± Frac of PWMavg. (After fully settling, the response variations will be from the ripple only and will remain within ± Frac/2 of PWMavg.) And it’s generally true that the more the ripple is attenuated, the larger Tfrac is. But for a given filter with two or more poles, there is an infinite number of combinations of component values that will limit the maximum ripple to Frac. (Think of the number of poles as being the number of capacitors in an R – C filter.) And yet the value of Tfrac is typically different for each combination. So we have a filter optimization problem: find the component value combination that minimizes Tfrac while satisfying the ripple requirement Frac.

I’ve addressed this issue before in a Design Idea (DI), but the procedure’s complexity was perhaps off-putting and inadequately flexible. I’ve since revisited the problem, finding a somewhat improved and analytically optimal solution. But that improvement alone does not justify a new DI.

So, why this new DI?

What I think does justify this is a spreadsheet that offers greater flexibility in terms of filter requirements and automates all the work for you. Download the files from https://github.com/Christopherrpaul/Customizable-PWM-Filter .

If you use OneDrive or something like it, you must install the files outside the OneDrive folder. (Safely ensconced there, OneDrive doesn’t “see” them and can’t interfere with the spreadsheet’s query of the paths to where certain files are stored locally.)

Open the spreadsheet. In the following, the yellow-highlighted parameters here and on the spreadsheet are inputs to be supplied by the user; the green-highlighted ones are spreadsheet outputs. Tell it your PWM frequency, in Hz, specify the required value of Frac, and press the “Calculate” button.

The Visual Basic Application (VBA)-driven spreadsheet takes that information and determines the values of the filter’s real and complex pole pairs ( the Q and ω0 of the latter ), which give you the optimal, smallest Tfrac, which it also displays.

To produce an implementable filter, it then combines this information with the (default) values of the filter’s capacitors c1, c2, and c3 . (These you can change and again press Calculate.) From all of this, it determines both the exact and the closest standard E96 values for the resistors r1, r2, and r3 needed to complete the filter. The filter itself is the third-order Sallen-Key low-pass depicted in the schematic portion of the spreadsheet screenshot seen in Figure 1.

Figure 1 A screenshot of the spreadsheet that runs the show. See the text.

And since we all like graphs, two have been provided. The one on top shows how ω0 and the real portion of all poles vary with Q. More importantly, it also shows that TFrac generally gets worse (larger) as Q is increased (not surprising, with the concomitant increase in oscillatory amplitudes).

The other graph shows the decay with time of PWMavg minus the absolute value of the transient response, with the voltage displayed on a logarithmic scale. The bumps are evidence of a damped oscillatory behavior.

But as they say in the late-night TV commercials (or at least they used to), “But wait! There’s more!”

How do I know this thing works?

You might ask how you can confirm that this filter will perform as advertised. The answer is easy if you’ve installed LTspice on your computer and you tell the spreadsheet the path starting from the root directory to the LTspice.exe file. Mine’s in C:\Users\chris\AppData\Local\Programs\ADI\LTspice\LTspice.exe.

Don’t worry if you can’t see the entire entry in the Excel cell provided. (NOTE – With the discussions surrounding the ongoing changes in LTspice versions 26.x.y, these files have been developed for use with the stable and still widely used LTspice 17.1.15. This version can still be downloaded and installed: https://ltspice.analog.com/software/LTspice64.exe. I haven’t checked if the files work with the 26.x.y versions.)

Press the “LTspice: Exact…” button. It will automatically launch a simulation using the exact resistor values derived and plot the filter’s response to the two biggest transients: a “full” one from 0 to 100% duty cycle (no PWM ripple) and a “half” one from 0 to 50% duty cycle (maximum possible ripple). See Figure 2 for a sample LTspice run.

Figure 2 An LTspice run using Exact component values for a sample filter.

The responses have been offset to reach their final values at 0 V. Tfrac appears on the plot as a vertical line along with two horizontal lines, which are at ± Frac. You can zoom in to see that the value of Tfrac is indeed correct; it crosses a ± Frac line exactly at the point that the full transition response does. (The full transition always takes a little longer to settle than the half-step transition.)

But alas, alack; this assumes perfect components with 0% tolerances. So the “LTspice Standard…” button launches a simulation of 100 Monte Carlo runs with capacitor and resistor tolerances of 1% and 1% using the E96 resistor values. (You can change all three of these default values and re-run the simulation. In fact, it’s worth considering the overall reduced settling time that can be had with suitably chosen 0.1% resistors added in series with small 1% resistors to more closely approach the exactly calculated values. Better tolerance capacitors would also help, but they tend to be prohibitively expensive.)

As you’ll see, non-zero tolerance variations lead to settling times longer than Tfrac. But by performing an extended number of Monte Carlo runs, you’ll be able to determine the time beyond which even filters made out of real-world components will have settled to Frac.

Filter design constraints

The real portions of all poles in the filter have been constrained to be identical. The reason for this is that these values control the decay rates of the half- and full-step transients, either of which could dictate the overall settling time. Given that the total ripple attenuation is the product of the real parts of both poles, if one were smaller than the other, it would extend the overall settling time beyond that achieved with identical poles. This constraint also simplifies the optimization problem in that there is only one real and one imaginary value of poles to consider, rather than one imaginary and two real values.

Calculated resistor values 

Depending on certain inputs to the spreadsheet, the derived values of the filter resistances might be smaller or larger than you’d like. In that case, the input values of the capacitors could be multiplied by a constant K of your choosing to obtain new resistor values divided by that K.

The spreadsheet’s default capacitor values are in the “Goldilocks” range—large enough that op amp input and PCB capacitances will affect them minimally, but small enough that NPO/COG type capacitors (whose stability with temperature and DC voltages are demanded in filter designs) are not prohibitively expensive. The ratios of one to the other of the default capacitor values have been shown to consistently result in realizable filters. Feel free to experiment with other values and ratios, but be aware that it might not be possible to realize filters with those changes.

Filter drivers

Do not drive the filter from a microprocessor directly. Its non-PWM functions draw currents that lead to small voltage drops across the IC-to-package-pin bonding wires. These induce errors by preventing signals from getting close to the ground and the supply rail. Instead, buffer the microprocessor with dedicated SN74AC04 logic inverters, which will swing to the rails, since they have no other currents to deal with and their outputs are minimally loaded. For a reasonably accurate reference voltage supplying the SN74AC04, consider the REF35.

SN74AC04-induced errors

It’s been pointed out that all digital drivers have different logic high and low resistances. These differences are sources of error that are worst at a 50% duty cycle. The part’s data sheet says that at a 3-V supply, the logic high voltage drop under a 12-mA load over the industrial temperature range could be as high as 560 mV, with a resistance of 45 ohms.

The logic low resistance maximum is a bit better, but there is no spec for the difference. The safe but admittedly ridiculous possibility is that the logic low resistance is 0 ohms, leaving us with a 45-ohm difference. This can be mitigated by paralleling G gates to reduce the drive resistance by that factor to produce a difference of Rdiff = 45/G.

Since no DC current can flow through the filter’s passive components, the fractional full-scale error at 50% is:

.5 · r1 / ( r1 + Rdiff) – .5 = – .5 · Rdiff / ( r1 + Rdiff)

For a b-bit PWM, you’d probably want the error to be less than half of one LSbit or 2-b-1. So you’d require that r1 > Rdiff · 2b.

Consider G = 5. For b = 8, r1 > 2300 ohms. For b = 12, it’s 37 kohms, and for b = 16, 590 kohms. But this brings up a second point: a large b means a relatively small fPWM and therefore a large TFrac. Fortunately, there’s a way around this.

Double up

Summing the contributions of two 8-bit PWMs, one of whose signals’ amplitude is 256 times that of the other, allows both to have an fPWM 256 times larger than that of a single 16-bit PWM. This yields a TFrac reduced by the same factor. Figure 3 shows one way to employ this approach.

Figure 3 Configuration with independent most significant (MSbit) and least significant (LSbit) 8-bit PWMs, the latter contributing 1/256 of the former, to replace a single 16-bit PWM. This arrangement reduces the settling time by a factor of 256.

Op-amp considerations

Figures 1 and 3 lead to the question of which op amp to use. A rail-to-rail input and output unit is warranted. The OPA376 family of singles, duals, and quads is a good answer.

It’s 25 µV at 25°C, ±1 µV/°C from -40 to +85°C, and barely disturbs the accuracy of even a 16-bit PWM. Its input bias current of 10 pA maximum at 25°C, and its typical (no maximum spec) of less than 50 pA at 85°C, introduces errors on par with its offset voltage. Consider the op amp’s output rail-to-rail limitations, however. Either avoid PWM duty cycles at the extremes, or extend the op amp’s supply rails a few tens of millivolts (see its data sheet) beyond those of the PWM.

In approaching your design, you might find the following nomograph in Figure 4 useful.

Figure 4 The above nomograph can aid in selecting the operating point of your design.

Problems, gripes, suggestions, requests, and accolades

The spreadsheet employs VBA numerical iteration routines to find the Q, ω0 pairs and the filter resistors. Although I’ve tested these routines extensively, it’s always possible that one or the other will fail to converge with some combination of input values.

In that case, please let me know by adding a note to the “Comments” section of this DI. This will generate an automatic email alert and will allow the inclusion in our conversation of others who might be interested. Please do not email me unless you have a comment that is truly meant to be private (a marriage proposal?) I encourage feedback of all kinds.

A grudging acknowledgement

I’d be remiss if I did not mention the help I got from a certain widely available AI program in developing this project. This ranged from deriving Inverse Laplace transforms and Newton-Raphson iteration algorithms to VBA coding.

But working with this AI wasn’t all lollipops and rainbows. In the course of the effort, I was reminded of Ronald Reagan’s admonition to “Trust, but verify.” But as things progressed, I dropped the “trust” part.

I found I had to break tasks down into sections, understand each that was provided, test assiduously, and make corrections before proceeding to the next step. Setting a multi-step task was a recipe for disaster. Still, AI is a valuable tool, and I find it even more valuable now that I better understand how to work with it.

I’d be interested in hearing about others’ experiences.

What is fashion tech? – diverse technologies and methods evolving the industry

“Fashion tech” is a term that combines fashion and technology. It refers to the use of big data, artificial intelligence (AI), augmented reality/virtual reality (AR/VR), and IT in customer services; the development of products incorporating functional materials and wearable devices; and the application of electronics and digital technologies in manufacturing, processing, and distribution processes.

Fashion tech is expected to garner even more attention as a means to invigorate future consumption activities, products, industries, and markets as technology progresses and new products and services are introduced. As mentioned earlier, fashion tech is a broad term, but it can be classified into two categories based on its nature. One is the evolution of services and customer experiences (CX), and the other is the evolution of product functionality and manufacturing processes. We explain these two aspects of fashion tech in the following sections.

Fashion tech evolving the customer experience (CX)

IT and digital transformation (DX) are currently driving fashion tech. There have been many challenges in enhancing sales CX in stores and on e-commerce sites, but many of these have been addressed through IT and DX initiatives.

For example, when selling clothing, shoes, jewellery, watches, eyewear, bags, etc., online, a longstanding issue has been the high hurdle for purchase decisions due to the difficulty for individual consumers to imagine how the actual products would look on them. However, in recent years, virtual fitting via AR (augmented reality), which can be easily used with smartphones and tablets, has become widely adopted. Even without 3D data for products, the technology to enable three-dimensional representation in AR using artificial intelligence (AI), if multiple 2D images of the product are prepared, has lowered the barrier to service introduction.

In parallel with virtual fitting, services are now emerging whereby AI assesses how well eyewear and accessories suit a consumer based on the individual’s facial features and the item’s shape and size. These technological advances are driving improvements in CX through the introduction of fashion tech.

Furthermore, the adoption of radio frequency identification (RFID) technology, including RFID tags and readers, is also advancing, and its applications are moving beyond rationalising inventory management. RFID is being used to reduce checkout lines and payment hassles by simplifying self-checkout and protecting brands, such as by authenticating genuine products.

Additionally, AI is being used to analyse customer and consumption trends across physical stores and e-commerce sites using RFID data. This enables a swift response to customer needs through appropriate inventory adjustments. These are just some of the ways technology is being used.

Fashion tech is evolving product value and manufacturing processes through technology

The DX and CX-oriented fashion tech mentioned above is expected to develop further. In addition, fashion tech that provides new added value to consumers through new characteristics and functions of materials and products is likely to garner more attention in the future due to advancements in materials, wearable devices, engineering, and manufacturing processes.

Here, we introduce technologies such as digital fabrication, smart textiles, smart fabrics, and wearables, which are said to be key to the future development of fashion tech.

Digital fabrication

Digital fabrication is a general term for technologies that make or process products based on digital data. In fashion product manufacturing, it refers to using 3D scanners and 3D CAD to digitise product ideas and patterns and then importing the digitised data into digital manufacturing machines such as 3D printers and laser cutters to shape or process the ideas and patterns.

Digital fabrication has attracted attention in recent years due to the diversification of needs and the development of digital technologies. By streamlining the design and manufacturing processes, digital fabrication has made it possible to accommodate high-mix, low-volume production and the manufacturing of personalised products. It is also gaining attention as a technology for providing new added value to products, such as the manufacturing and processing of materials with structures, functions, and properties that were not previously available.

Smart fabrics (smart textiles)

Expectations are rising for smart fabrics or smart textiles (hereinafter, smart fabrics), technologies that create new added value by imparting functionality to fashion products’ materials themselves. The digital fabrication mentioned earlier is also a means to realise these technologies.

Smart fabrics generally refer to imparting functionality to fibres by integrating electronic technology. The functions are diverse. For example, the clothing itself may function as a sensor to monitor the wearer’s health condition, use electricity for sterilisation, or regulate temperature. Various R&D and commercialisation efforts are underway to realise these functions.

Many of these technologies are attracting attention for a wide range of purposes, such as health and medical care, sports and fitness, and safety improvement. The introduction of such technologies into everyday clothing is being plotted to provide new added value through fashion products with advanced functionality.

Wearable and flexible electronics

The integration of wearable devices into fashion items and the IoT-ization of fashion items themselves are also anticipated as a technology closely related to smart fabrics. For instance, by using wearable devices to process, communicate, display, manipulate, and control data sensed by smart fabrics, products could be endowed with a variety of functions and performance.

Many wearable devices, such as smartwatches, have rigid mounting boards and housings, which is fine for wristwatches. However, these rigid components can interfere with body movement and risk device damage when implemented in wearable items such as clothing.

One promising solution to such challenges is flexible electronics. Flexible electronics refer to pliable electronic circuits and components that can bend. This high compatibility with smart fabrics and wearables raises expectations for their application to future fashion tech and the sophistication of functions it will bring.

Fashion trends cyclically go through revivals. It is hard to imagine that futuristic designs like something out of a sci-fi movie will suddenly become mainstream. This is likely because established designs are rational and fit most people’s sensibilities. On the other hand, while the outward appearance of items may follow traditional lines, the purchasing experience, product functionality, and added value will continue to evolve through fashion tech.
