Patent ID: 7957214

Claim:
A voltage regulator for providing a temperature-dependent regulated output voltage, the voltage regulator comprising: a comparator having a reference voltage input, a feedback input, and an output, the comparator configured to generate an output voltage in accordance with a comparison between a reference voltage applied to the reference voltage input and a feedback voltage applied to the feedback input; a driver coupled to the output of the comparator and an output node, the driver configured to receive the output voltage from the comparator and drive the regulated output voltage at the output node according to the output voltage from the comparator; an impedance coupled to the comparator and the output node, the impedance configured to establish the feedback voltage applied to the feedback input of the comparator, based at least in part on a current through the impedance; and a modulator coupled to the impedance and configured to adjust the current through the impedance based, at least in part, on a temperature proximal to the modulator.
