Patent ID: 7719344

Claim:
A stabilization system for substrate potential regulation for an integrated circuit device, said stabilization system comprising: a comparator operable to compare a reference voltage to a ground voltage of the integrated circuit device; a negative charge pump coupled to the comparator, wherein an output of the comparator is coupled to an input of the negative charge pump, wherein the negative charge pump is controlled by the comparator and operable to drive down a potential of a substrate of the integrated circuit device when the reference voltage is greater than the ground voltage; and a stabilization component coupled to the input of the negative charge pump and the output of the comparator, wherein the stabilization component is operable to shunt current between the substrate and a ground of the integrated circuit device to correct an over-charge of the substrate by the negative charge pump, and wherein the stabilization component is further operable to shunt the current responsive to detecting that a duration of the over-charge exceeds a predetermined number of clock cycles.
