An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of ...

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

In most operational amplifier (op amp) circuits, the resistor tolerance and resistor temperature coefficient determine the gain accuracy and gain temperature drift (Figure 1 shows a typical circuit).

Designers of instruments or control systems often find that component performance limits overall equipment performance in areas such as stability, frequency response, noise, and ESD. This is ...

Abstract: We present a new design of an electronically tunable linear MOS resistor circuit that operates in the subthreshold saturation region, supported with mathematical derivations and simulation ...

A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...
