Abstract
An oscillation sensor for a regulator that provides dynamic control of a connection/disconnection of a compensation capacitance. The compensation capacitor is disconnected under normal operation and is automatically connected if oscillation is detected in the output and regulator's error amplifier. In this way, oscillations are stopped in the regulator almost immediately after it occurs. Also, once the circuit is stable again, the compensation capacitor is quickly disconnected again. Consequently, the compensation capacitor does not adversely affect the overall performance of the regulator.
