Chopper amplifiers are generally considered as a perfect choice in applications where DC precision is mandatory. This kind of amplifier uses a continuous time modulation technique to exhibit extremely ...
Editor’s note: We continue with the second part of Chapter 26, Applications considerations and circuits for a new chopper-stabilized op amp. Part 1 of this chapter can be found on EDN online. This ...
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 ...
Zero-drift amplifiers dynamically correct their offset voltage and reshape noise density. Two commonly used types—auto-zero amplifiers and choppers—achieve nanovolt-level offsets and extremely low ...

VOLTAGE REFERENCES generate wideband noise spectrums. For most semiconductor devices, this spectrum usually has a wideband “white noise” component with relatively constant power density versus ...
Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...
