We found this circuit in a Radio Electronics magazine from December 1969. The circuit uses a low-power MOSFET that is not very common today.
We found this circuit in a 1992 publication, but for the components it uses, its assembly can...
We found this interesting configuration in a 1976 technical documentation. Equivalent diodes can...
The original application of this 1967 Ferranti circuit can be changed so that it functions as a pass...
