Patent ID: 6975099

Claim:
A voltage regulator comprising: an output stage having an input and an output, the output operable to provide a regulated output signal; a first stage having a first input, a second input, and an output, the first input operable to receive a signal reference voltage, the second input operable to receive a compensated signal derived from the regulated output signal, and the output operable to generate a first-stage output signal based at least in part on the first and second inputs; a second stage having an input and an output, the input operable to receive the first-stage output signal and the output operable to generate a second-stage output signal received at the input of the output stage; a voltage divider coupled to the output stage output, the voltage divider having at least two circuit elements in series and forming a compensated output at the circuit node between the at least two circuit elements, whereby the compensated signal derived from the output signal is generated at the circuit node; a first compensation unit coupled between the first-stage output and the output-stage output; and a second compensation unit coupled in parallel with one of the circuit elements of the voltage divider.
