From instrument amplifiers to precision analog circuits to geophones, resistor networks are used in a variety of applications. Each has its own unique requirements, but none more stringent than the ...

In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

Although there are several ways to sense current flowing from a source such as a battery, or to a load such as a motor, the current-sense resistor is among the most widely used approaches. There are ...

Measuring dynamic currents with an oscilloscope is challenging, but this updated differential current probe makes it simple ...

A fourth circuit element called memristor (the first three being resistors, capacitors and inductors) has been proposed since 1971, but HP labs has finally made a working physical model of the thing.

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...
