Abstract
A voltage regulator uses a digital feedback technique to regulate the voltage at an output of the regulator. The voltage level of an output signal is measured. The voltage level of the output signal is compared to a first reference voltage. A programmable digital control logic block regulates the voltage level of the output signal and operates in a first mode if the voltage level of the output signal is above a first reference voltage and in a second mode if the voltage level of the output signal is below the first reference voltage. Depending on the mode of operation, the programmable digital control logic block provides digital control signals to other elements of the feedback loop.
