This PLL with operational amplifiers was found in 1969 documentation. The configuration can be adapted to use modern components. The circuit has a gain of 15 V / V and can operate with 10 kHz signals.
This simple transistor gain test acts as an oscillator for the transistor under test. The circuit is...
