ABSTRACT:
An integrated circuit and method in an integrated circuit for providing electrical power utilizing digital power regulation. Various aspects of the present invention provide an integrated circuit comprising a power supply module that outputs electrical power at an output voltage level. An error determination module may receive a power supply reference signal and a signal indicative of the output voltage level and output a power supply error signal. A digital controller module may receive the power supply error signal, digitally process the power supply error signal, and output a power supply control signal. A power output-monitoring module may monitor the electrical power output from the power supply module and output the signal indicative of the output voltage level. The power supply module may receive the power supply control signal and output the electrical power based, at least in part, on the power supply control signal.
