Patent ID: 7242169

Claim:
A voltage regulator, comprising: a first amplifier comprising: a first input electrically connected to a first node; a second input electrically connected to a third node; a first output; a second amplifier comprising: a first input electrically connected to a fourth node; a second input electrically connected to a second node; a second output; an offset generator comprising: a first input electrically connected to the first output from the first amplifier; a second input electrically connected to the second output from the second amplifier; a third input electrically connected to a reference voltage; an offset output associated with an offset reference voltage and connected to an offset output node; a compensation amplifier comprising: a first input electrically connected to the first node; and a second input electrically connected to the offset output node; wherein the compensation amplifier is operative to drive a voltage at the first node to match the offset reference voltage.
