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 ...

There are many ways to build a radio receiver, but most have a few things in common, such as oscillators, tuned circuits, detectors, mixers, and amplifiers. Put those together in the right order and ...

One of the primary goals when designing dc/dc conversion circuits is to get a high conversion efficiency. Without careful design, it is easy to dissipate as much energy in the conversion circuit as ...

Chop the noise gain to measure an op amp’s real-time offset voltage introduces a new type of chopping. “Chopping the noise gain” is a simple way to measure the offset voltage in real time, so that you ...
