ABSTRACT:
A circuit having a first integrator 46 and a sensor 20 for sensing a difference between an output voltage of the first integrator and a trip voltage provides a signal indicative of whether the output voltage is greater than the trip voltage. Resetting circuitry 40, 42 and 44 is coupled to the sensor 20 for softly bringing the output voltage lower than the trip voltage when the signal from the sensor 20 indicates that the output voltage is greater than the trip voltage.
