Found in a 1966’s General Electric documentation, this circuit uses a triple diode from the time. The output current is 5 mA. It serves as a voltage reference.
We found this circuit in an old American publication. The transistors can be BC558 and diode 1N34....
This simple circuit operates with only 1.5 volts of a battery and detects low resistance making a...
The cascade connection of two flip-flops allows division by 4, as shown in the figure. Note that...
