A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Successful high-speed circuit designs need the right combination of grounding, power-supply bypassing, and decoupling. Modern op amps have much higher operating bandwidths than their predecessors.

This document is an application note of the Printed Circuit Board (PCB) layout techniques in operational amplifier precision design. It discusses the PCB effects experienced in high DC precision op ...

A continuity tester, as found on most multimeters today, is a great tool for finding broken connections and short circuits. But once you’ve found a short, it’s up to you to figure out which part of ...

While choosing an op-amp buffer for a new high-resolution single-supply DAC, a source of negative supply was considered because the buffer op-amp had to provide true zero voltage on its output. Wow ...
