Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

Oscillation and peaking occur primarily when op amps that are not properly compensated are used to drive large capacitive loads. The other results from this situation are lower bandwidth and lower ...

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 ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

In 2008, Bob Pease exchanged e-mails with Linear Technology’s Mark Thoren, me, and a few other friends. The subject was how an amplifier will oscillate if you put a capacitive load on it. Bob knew ...

It is a familiar situation. An application needs an amplifier with excellent output drive capability, say several hundred milliamps, to drive a large capacitive load. The supplier’s engineering team ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...

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 ...
