Video Description

Back to basics introduction to the differential amplifier, aka the diff-pair, long-tailed pair, emitter coupled pair, etc. The basic operation of the circuit is presented, along with a simple mechanical simulation. Also, how the addition of current sources and mirrors can be used to address some of the performance issues, and begin to form the rudimentary beginnings of an op amp. This is the follow-up video from "teaser" video published earlier. Teaser video: http://www.youtube.com/watch?v=zhM3rPHFgt4 Video note pages: http://www.qsl.net/w2aew/youtube/longtailedpair.pdf
