This circuit uses a quadruple operational amplifier of the time. The circuit is from the 70s but can be implemented with modern operators that require the use of a symmetrical source.
The circuit in the Multisim Blue simulation sources a regulated voltage to loads up to 50 mA. The...
This circuit was found in a PC documentation from 1996. It can be used as a shield with modern...
Based on 74HC digital circuits, this circuit generates signals in three phases. The frequency...
