We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and ...

Modeling on Mondays: A Comprehensive and Speedy Op-Amp SPICE Model Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired—until ...

We analog designers take great pains to make our amplifiers stable when we design them, but there are many situations that cause them to oscillate in the real world. Various types of loads can make ...

Slewing behavior of op amps is often misunderstood. It’s a meaty topic so let’s sort it out. The input circuitry of an op amp circuit generally has a very small voltage between the inputs—ideally zero ...

The ordinary modern IC op amp is fully applicable to most standard amplifier configurations. Error sources are small and may be of no concern, or one can easily ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...
