Single op amp oscillator


Posted on Jul 2, 2012

This circuit has a Schmitt trigger and integrator built around one op amp. Timing is controlled by the RC network. Voltage at the inverting input follows the RC charging exponential within the upper and lower hysteresis levels. By closing the switch SWI, the discharge time of the capacitor becomes ten times as fast as the rise time
