Abstract
A voltage regulator circuit included in a computer system may include multiple phase circuits each coupled to a regulated power supply node via a corresponding inductor. The phase circuits may modify a voltage level of the regulated power supply node using respective control signals generated by a digital control circuit that processes multiple data bits. An analog-to-digital converter circuit may compare the voltage level of the regulated power supply node to multiple reference voltage levels and sample the resultant comparisons to generate the multiple data bits.
