An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

As part of our Op-Amp Challenge we’re seeing a wide diversity of entries showcasing the seemingly endless capabilities of these extremely versatile parts. Another one comes from [Joseph Thomas], who ...
