ABSTRACT:
A circuit and a method for detecting noise events in a system with time variable operating points is provided. A switched capacitor filter comprising a plurality of capacitor units, samples a first voltage to determine an average of a set of voltage measurements, forming an average voltage. A filter control unit controls the plurality of capacitor units in the switched capacitor filter. A comparing unit compares the average voltage to the first voltage to form a comparison. A signaling unit generates a signal to instruct circuits in a processor to initiate actions to keep the first voltage from drooping below a threshold level in response to the comparison.
