When available fixed-gain values match design requirements, a PGA (programmable-gain-amplifier) IC offers a drop-in choice, but what does a designer do when a suitable PGA is unavailable? Before the ...

A precision voltage divider produces a specific fraction of its input voltage using carefully matched resistive components.

If you’ve ever worked with guitar pedals or analog audio gear, you’ve probably realized the value of a resistor decade box. They substitute for a resistor in a circuit and let you quickly flick ...

"Learn how to set up and analyze an RC circuit using the PhET Simulator! In this tutorial, I’ll guide you through the step-by-step process of building a simple resistor-capacitor circuit, explaining ...

Members can download this article in PDF format. The vision of electric vehicles (EVs) as a primary transportation platform is slowly coming of age. EVs are moving away from being seen as eclectic to ...

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 ...
