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 ...

Analog and mixed-signal designers have been confronting amplifier 1/f noise as well as DC offset and drift challenges in their circuit designs since the time of the introduction of semiconductor ...

What is a chopper-stabilized operational amplifier (op amp)? Chopper-stabilized amps constantly correct low-frequency errors across the inputs of the amplifier. This makes them attractive alternatives ...

A chopper stabilized amplifier is an electronic circuit that employs a modulation technique to reduce or eliminate dc offset and low-frequency noise in op amps. Modern chopper-stabilized op amps ...

Editor's note: This article will be in two parts. This Part 1 will discuss latest advances in 'Zero-Drift' Op Amps and Noise. Self-correcting or ‘Zero-Drift’ operational amplifiers, as this device ...
