Was hoping someone could sum up what parasitic oscillations are (perhaps in terms of some simple circuit equations/models). Currently studying basic Op Amp circuits and during the lab the instructors mentioned this term and everyone seemed to magically know what it refers to(adsbygoogle = window.adsbygoogle || []).push({});

Also, in the labs we are looking at feedback with closed looped Op Amp circuits (where Gain = Rf / Ri), just having troubles with the terms, "closed loop gain" and "open loop gain".

Cheers for any explanations.
