An apparatus and method for regulating a voltage to a load to compensate for one or more parasitic impedances. A first amplifier measures the voltage drop due to a first parasitic impedance, and a second amplifier measures the voltage drop due to a second parasitic impedance. An offset generator sums the first and second voltage drops with a reference voltage, and drives a DC-to-DC converter to produce an input voltage matching the summed voltages. Accordingly, the voltage at a load between the parasitic impedances matches the reference voltage. The load may be, for example, a computer microprocessor or central processing unit.
