Abstract
In certain aspects, a regulator includes a variable-impedance switch coupled between a supply rail and a circuit block, wherein an impedance of the variable-impedance switch is set by an impedance code input to the variable-impedance switch. The regulator also includes an analog-to-digital converter (ADC) configured to convert a block supply voltage at the circuit block into a voltage code, and a controller configured to adjust the impedance code based on the voltage code in a direction that reduces a difference between the block supply voltage and a target supply voltage.
