Clock generator boosts GPS accuracy

EDN Network - 48 min 51 sec ago

With a built-in MEMS resonator, SiTime’s Symphonic SiT30100 mobile clock generator replaces up to four discrete timing devices. It provides accurate clock signals for 5G and GNSS chipsets in mobile and IoT devices such as smartphones, tablets, laptops, and asset trackers.

An integrated temperature sensor feeds precise data to compensation algorithms, helping maintain clock stability. This improves GPS accuracy and reduces lock time, enabling stable performance even in harsh environmental conditions.

The SiT30100 delivers four clock outputs at 76.8 MHz, 38.4 MHz, or 19.2 MHz—configurable from any output—for baseband, RF, and GNSS applications. By eliminating the need for an external resonator, the SiT30100 enables a compact 2.22-mm² single-chip solution. Multiple Output Enable pins allow selective output control to reduce power consumption and minimize EMI. The device also features a temperature-to-digital converter with a single-wire UART interface for system-level temperature compensation, supporting frequency stability down to ±0.5 ppm.

The Symphonic mobile clock generator is available now in a 10-pin chip-scale package.

SiC MOSFETs reinforce system longevity

EDN Network - 48 min 56 sec ago

Navitas Semiconductor’s latest GeneSiC MOSFETs exceed AEC-Q101 standards, extending lifetime in automotive and industrial systems. Based on trench-assisted planar technology, they are available in HV-T2Pak top-side cooled packages with 6.45-mm creepage and a CTI above 600 V, supporting IEC-compliant operation up to 1200 V.

Navitas uses the term AEC-Plus to designate parts that exceed the AEC-Q101 reliability tests published by the Automotive Electronics Council (AEC), based on multi-lot stress-test results. This in-house benchmark layers additional stress conditions onto standard AEC-Q101 and JEDEC protocols to better mirror real-world automotive and industrial mission profiles by:

  • Incorporating dynamic reverse bias (D-HTRB) and dynamic gate switching (D-HTGB) tests
  • Running power- and temperature-cycling for over twice the standard duration
  • Extending static high-temperature, high-voltage tests (HTRB, HTGB) to over three times the AEC-Q101 interval
  • Qualifying parts to 200 °C TJMAX for improved overload capability

Housed in the 14×18.5-mm HV-T2Pak, the initial portfolio includes 1200-V devices with on-resistance from 18 mΩ to 135 mΩ and 650-V devices ranging from 20 mΩ to 55 mΩ. Lower on-resistance (<15 mΩ) SiC MOSFETs in the same package will follow later in 2025. For more information on GeneSiC MOSFETs, click here.

3D ultrasonic sensor improves robot safety

EDN Network - 49 min 2 sec ago

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile robots (AMRs) to safely navigate around people and objects.

The beamforming technology behind ADAR—used in SONAR, RADAR, and medical imaging—has been under development at Norway’s MiNaLab research center for over 20 years and is now adapted for in-air ultrasonic sensing.

ADAR empowers autonomous robots with omnidirectional depth perception, enabling them to ‘hear’ their surroundings in real-time 3D using airborne soundwaves to interpret spatial information. The sensor forms a 5-meter virtual shield that helps people and robots safely share space. It combines wavelength-matched transducers with efficient signal processing for beamforming and object recognition.

The 3D ultrasonic sensors offer a cost-effective alternative to LiDAR and camera-based systems, typically consuming just 5 W and performing more reliably in challenging conditions such as poor lighting, dust, and temperature fluctuations.

Sonair’s ADAR sensor is developed in accordance with ISO 13849-1:2023 PLd / SIL2, with safety certification expected by year-end. The company will unveil the sensor to North American audiences at Automate 2025, with shipments scheduled to begin in July.

High-power laser diode targets bio diagnostics

EDN Network - 49 min 4 sec ago

Designed for life science applications, the PLT5 488HB_EP cyan laser diode from ams OSRAM delivers 300 mW of output power at 488 nm. It offers five times the optical output and over 40% higher efficiency than its predecessor—key for DNA sequencing, flow cytometry, and other diagnostic tasks.

According to the company, cyan light effectively stimulates fluorescent dyes in diagnostic devices like flow cytometers and blood testing equipment. The laser diode provides precise wavelength control of ±2 nm, ensuring accurate results in diagnostics, and features a high modulation bandwidth that enhances both signal quality and the speed of analytical processes. Additionally, the PLT5 488HB_EP has low thermal resistance, enabling reliable operation at high temperatures.

While well-suited for life science research, the cyan laser diode also shows potential in other applications. In stage and stadium lighting, for example, it expands the color gamut, producing more vivid visual effects. In fluorescence microscopy, the 488-nanometer wavelength enhances visibility, making it easier to observe fine details that may be difficult to detect with conventional light sources.

Converting square-waves into saw-teeth

EDN Network - Thu, 05/08/2025 - 17:00

Generating analog sawtooth waveforms (linear ramp followed by a quick reset to zero) from digital timing signals is a common function. It usually requires a negative supply as sketched in Figure 1, where Vsaw = -(-V) Tsq/(R1C1).

Figure 1 The usual topology for converting digital square waves to analog sawtooth requires a negative rail.

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

Negative current through R1 ramps up inverting integrator A1’s output until switch U1 resets it to zero. This topology is simple and works well, but it has the disadvantage of needing a separate negative rail so the integrator can be referenced to ground. Also, the RC network in front of U1, which needs to differentiate the positive edge of the square wave, is kind of messy and less than precise.

Figure 2 shows an alternative sawtooth topology that employs flying capacitor C2 to reset A1. This allows it to be referenced to the positive rail instead of ground, eliminating the need for Figure 1’s negative rail and pulse differentiation. Here’s how it works.

Figure 2 Flying capacitor C2 resets the RRIO ramp to zero volts, allowing it to be referenced to the positive rail instead of ground.

RRIO op-amp A1’s positive input being tied to the VL positive rail allows R1 to act as a current sink between ground and A1’s summing point. This ramps A1’s output positively to:

Vsaw = VL Tsq / (R1C1)

Simultaneously, flying capacitor C2 charges to Vsaw via its connection to A1’s output through U1a. Then, on the positive-going edge of “Square In,” the bottom end of C2 is connected to A1 summing point while its top end switches from ground to VL. This dumps a quantum of charge into C1:

(VL + (Vsaw – VL))C2 = VsawC2

Given that C1 = C2, this resets “Saw Out” to ground as shown in Figure 3.

Figure 3 “Square In” and “Saw Out” voltage waveforms where Vsaw = VL T/(R1C1).

For best accuracy, R1, C1 and C2 should be precision types.

Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Over 100 submissions have been accepted since his first contribution back in 1974.
