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 ...

So, what is a resistor? A resistor is a material that resists, limits or impedes the flow of electrical current. Resistive materials include carbon and various metallic alloys such as nichrome.

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; ...
