This circuit can be used to obtain a zener voltage from a common zener of another value, adjusting in a multimeter. The circuit is from an American documentation of the 1970s.
This circuit uses only passive components calculated for the desired frequency. We found it in an...
The circuit is from the 1990 Motorola Linear Databook. The circuit can be implemented with other...
