Op Amp History - The Operational Amplifier - From Abstraction to Reality

Welcome to the video series The Operational Amplifier - From Abstraction to Reality. Operational amplifiers are the workhorse of the analog industry. It is straightforward for the engineer to design circuits by using a set of assumptions about the device, and therefore using simple formulas to calculate the values of the surrounding components. However, in the real world, there are limitations and errors that must be understood. This is where reality sets in. 00:00 Introduction 00:31 Invention of Negative Feedback 03:20 Inherent Gain Variation Fixed By Negative Feedback 04:10 Control Theory Model of Negative Feedback 05:43 Closed Loop Gain 06:38 Throwing Away Gain is CRAZY 07:10 Gain Stabization 09:06 Philbrick K2-W Vacuum Tube Operational Amplifier 11:16 Philbrick K2-W General Specifications 14:15 1st Monolithic Op-Amps 16:45 Today's Availability of Op-Amps is Daunting
