This step of good gain was obtained in an American publication of the 1980s. The circuit can be powered by voltages from 3 to 9 V and the FET can be of almost any type.
This circuit is characterized by its low input impedance and voltage gain below the unit. The...
We found this circuit in old documentation. Modern equivalent operational amplifiers can be used....
We found this circuit in the Radio Electronics magazine of December 1972. It generates signals in 6...
