This circuit shows that we can implement a voltage-controlled oscillator with almost any CMOS that can be connected as an inverter. The circuit is from Radio Electronics from January 1987.
This circuit can be used to receive signals from CB18636E and other modulated light transmitters in this...
Due to its low working voltage, this circuit of an old EDN can be associated with a...
We found this circuit in a 1983 English magazine, but it can be easily assembled with the BC548...
