This power supply was found in a RCA publication from the 1970s. The circuit uses transistors from that time. Modern equivalent transistors can be used.
This circuit was found in the SGS manual of linear integrated circuits of 1982. The CMRR depends on...
In the figure we have a receiver for frequency modulated light signals (see the transmitter in...
In the figure we have a high stability voltage reference, providing a voltage of 10 V at the...
