VOLTAGE MONITORING CIRCUIT THAT MANAGES VOLTAGE DRIFT CAUSED FROM NEGATIVE BIAS TEMPERATURE INSTABILITY

摘要

Regulating voltages at inputs of an electronic device by performing at least the following: receiving, at a voltage monitoring circuit (210), a monitoring voltage corresponding to a power system, determining, at the voltage monitoring circuit, whether the monitoring voltage is equal to or exceeds a monitoring threshold voltage, (204) receiving, at the voltage monitoring circuit, an output indicating whether an inputted reference voltage and an inputted feedback voltage at a comparator circuit differs, (218) regulating, at the voltage monitoring circuit, a feedback voltage to match the inputted reference voltage, (204) and providing, from the voltage monitoring circuit, the feedback voltage as an updated inputted feedback voltage for the comparator circuit (220).
