This amplifier is from Motorola's 1990 Linear Databook. The circuit can be used with operating amplifiers with the same characteristics and the power supply must be symmetrical.
This configuration was found in an English magazine from 1965. It is valid for any junction FET. The...
This circuit for a frequency of 1 kHz uses a symmetrical source. Other operational circuits can be...
The transistors in this circuit from a 1994 technical publication may be BC548 and the 12 V supply...
