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.
This circuit was found in a 1969 Mullard documentation. Used transistors can be replaced with...
Found in General Electric's documentation from 1970, this circuit is indicated for the so-called...
The improvement we found in this stage on a common basis is the use of only one power supply. The...
