This circuit consists of two stages that each shift 180 degrees the signal. The circuit was proposed by Siliconix in a 1966 publication. Equivalent FETs can be used.
We found this circuit in the March 1992 issue of Radio Electronics magazine. The circuit has a...
The circuit presented may use any general purpose transistor. The indicator is an LED and...
This unusual audio amplifier configuration was obtained in a 1974 documentation. The PNP...
