Abstract
A method of regulating a supply voltage (Vgg) provided to a load circuit. The method can include generating at least one reference voltage (Vr1, Vr2, Vr3) having a negative voltage-temperature coefficient. The method further can include applying the reference voltage as a bias voltage (Vbias) to a current sink that is electrically coupled in parallel with a path of a leakage current (Ileak) drawn by the load circuit. A related voltage regulator can include a current sink that is electrically coupled in parallel with a path of a leakage current drawn by a load circuit, and a bias control circuit that generates at least one reference voltage having a negative voltage-temperature coefficient and applies the reference voltage as a bias voltage to a current sink.
