Found in a 1967 documentation this circuit can be applied to any operational amplifier. Components without values determine the frequency to which the circuit is tuned.
We found this circuit in a technical documentation from the 70's. Any double-gate MOSFET can be...
We found this thyristor power supply in a 1987 documentation. It uses common SCRs as rectifiers and...
This simple circuit has its trigger point set in the trimpot. The transistor can be any general...
