This circuit was found in a 1967 General Electric documentation. Tunnel diodes can oscillate at very high frequencies. These are not currently easy to obtain components.
We found this circuit in a 1988 documentation, but the components used are still current. The...
This simple timer uses one of the six inverter ports on a CMOS integrated circuit. Rx and Cx...
With an output power of 1.5 W under a 12 V supply, this circuit makes use of transistors that are...
