oscillator circuit with opamp and zener diode


Posted on Feb 5, 2014

Looks like a schmitt trigger oscillator. By the way the resistors and capacitor are used it is probably a saw-tooth wave generator with R2 & R3 determining the slope of the rising and trailing edges. The zener helps control the amplitude between 0 to 3V OR maybe it chops off the tops of the sawtooth wave thereby creating an output that has a trapezoidal waveform.
