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

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 ...

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC ...

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 ...
