Chua’s circuit is the simplest electronic circuit that produces chaos—the output of this circuit never repeats the same sequence, and is a truly random signal. If you need a good source of randomness, ...

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.

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 ...

This video explains the physics behind reversed resistor and capacitor equations. We clarify why voltage–current relationships appear inverted in different contexts, connect the math to physical ...

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 ...

Researchers developed a compact, low-noise bandgap reference using a single resistor, improving stability and efficiency for ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
