We found this configuration in documentation from the 1980s. It applies to almost any operational amplifier and in this version requires a symmetrical power supply.
The circuit is from the 1990 Motorola Linear Databook. The circuit can be implemented with other...
We can obtain the characteristics of an operational amplifier with FET by adding FETs common to the...
This interesting circuit for testing signal transistors with the oscilloscope was found in the...
