Varactor diodes are our varicaps of today. This circuit for switching signals in an RF circuit was found in a Radio Electronics magazine from July 1982.
This voltage inverter was found in a 1960's Mullard manual. The transistors are from that time. No...
We found this sine wave oscillator in the December 1995 issue of Electronics Now. The circuit uses...
The circuit shown must be supplied with voltages of 4.5 to 5 V and generates signals up to a...
