Abstract
A system that includes a regulator unit is disclosed. The regulator unit includes first and second phase units whose outputs are coupled to a common output node. Each of the phase units may be configured to source current to the output node in response to the assertion of a respective clock signal in order to generate a regulated supply voltage. Each phase unit includes a respective transconductance amplifier configured to generate a respective demand current dependent upon a reference voltage and the regulated supply voltage.
