Review of Razavi: Electronic Circuits 1 Video Lectures, Block Op Amps

These are the last 4 videos of Razavi's Electronic Circuits 1 video lectures. All 4 are about Op Amps. They mostly do not depend of the previous video lectures. He starts with very simple explanations, but some parts are quite advanced. For example, he gives not only the equation for the "textbook" integrator (the one that will not work in reality because of saturation). He also develops the equation for said integrator with an additional resistor in parallel to the cap. But even if you stick to the more simpler parts of his lectures, you can learn a lot - he takes his time to explain everything very thoroughly.
