Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, taking the form of conductive plates separated by an insulating material ...

In Part 1 (click here), we learned how an old technique known as servo feedback can remove dc offsets in a dc-coupled gain block, without putting any components, especially capacitors, in the ...

One of the most, if not the most, basic component of any power management system is the capacitor. It serves three functions: Shape frequency response Store energy Deliver current instantaneously ...

The hysteretic power supply is simpler than the voltage- or current-mode closed-loop-control dc-dc switchers, although its simplicity may be a bit deceiving due to component variations and potential ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...

The Colpitts oscillator is a time-tested design — from 1918. [The Offset Volt] has a few videos covering the design of these circuits including an op-amp and a transistor version. You can find the ...
