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 ...

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 ...

Without careful design, it is easy to dissipate as much energy in the conversion circuit as gets delivered to the load. The dc/dc conversion method of choice for moderate power output is often a ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
