There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...
Switch-mode power supplies (SMPS) are known for their superior efficiency. And while they achieve a significant level of efficiency, the quest to improve it even further continues to march on. One ...
Earlier this week, Californian company Pre-Switch claimed 99.3% efficiency for a 100kHz electric vehicle traction inverter running at 100kW. It credits this impressive figure to the use of a resonant ...
Field-effect transistors based on carbon nanotubes have been shown to be faster and less energy consuming than their silicon counterparts. However, ensuring these advantages are maintained for ...
Announced yesterday, researchers from Surrey and Cambridge universities and the National Research Institute in Rome have used thin-film source-gated transistor (SGT) to create compact analogue circuit ...
