Embedded passives enhance vertical power delivery
Saras Micro Devices has developed technology to embed capacitors and inductors into semiconductor substrates and PCB laminates. Doing so keeps them close to loads through vertical power delivery, Every day, we hear about the need for more power to satisfy AI chips. The combination of low voltage and high current (1000s of amps) means that […]
What is the antiresonance effect in power supply capacitors?
The antiresonance effect can be a bug or a feature. In the case of DC link capacitors in high-frequency converters, it’s a bug that can decrease performance. But antiresonance in ultrasonic transducer power supplies is a feature used for efficient, stable power delivery under varying loads. Beyond the resonant frequency of a capacitor, parasitics in […]
