A Peek Inside the Operational Amplifier (4k Video)

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. This video gives some insight into the inner working of the operational amplifier to help understand its specifications and limitations. 00:00 Intro 00:47 Differential Pair AKA Long Tailed Pair 05:45 Common Mode Rejection 06:30 Constant Current Source With Common Mode Inputs 07:07 Single Ended Output 08:06 Bipolar Junction Transistor Transconductance 09:12 Current to Voltage Converter 10:07 Innovation of the Current Mirror 10:29 Current Mirror on the Bench 11:31 Additional Gain Stage 12:38 Output Stage 13:07 Common Mode Input Range 14:09 Maximum Output Voltage Swing CORRECTION: 08:06 The transistor schematic symbol should have been a NPN not a PNP
