Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...
In Seemingly Simple Circuits: Transresistance Amplifier, Part 1– Approximating Op-Amps, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, ...
