This circuit with two operating modes was found in the September 1989 issue of Radio Electronics magazine. Other operational amplifiers can be used. The power supply must be dual.
The components used in this 80's circuit are not common today. The circuit is very sensitive and must...
This circuit is from the 1993 Linear Technology Applications. We can implement the same oscillator...
We found this circuit in a 1967 Electronic Design. The circuit used a MOSFET of the time, which is...
