Introductory courses on noise in electronic circuits often start by stating the following formula for the open-circuit noise voltage of a resistor: You’ll probably argue that’s a lot of conditions; ...

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.

What kinds of applications utilize precision resistor trimming? Obvious applications include setting operational-amplifier gain and offset and voltage regulator output (Fig. 1a and 1b). But there are ...

Hackaday Editors Elliot Williams and Tom Nardi meet up virtually to talk about the week’s top stories and hacks, such as the fine art of resistor trimming and lessons learned from doing overseas ...

Sponsored by Texas Instruments: Precision management of battery systems requires solutions such as resistor dividers, which offer remarkable specs to meet design demands. The vision of electric ...
