Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

In electrical and electronic engineering, capacitors are fundamental components. They appear across all manner of applications, including power supplies, analogue filters, timing circuits, and energy ...

The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...

All buck converters need capacitors on the input. Actually, in a perfect world, if the supply had zero output impedance and infinite current capacity and the tracks had zero resistance or inductance, ...
