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 ...
Op amps with low input capacitance are required in applications such as smoke detectors, photodiode transimpedance amplifiers, medical instrumentation, industrial control systems, and the piezo-sensor ...
Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...
