1. A semiconductor device comprising:
an analog voltage regulator configured to generate an analog reference voltage and a regulated output voltage; and
an integrated circuit module configured to generate an analog sense voltage based on the regulated output voltage, the integrate circuit module including:
a plurality of integrated circuit dies;
a first sensor configured to generate a digital reference voltage based on the analog reference voltage;
a plurality of second voltage sensors configured to detect voltages at predetermined locations on the integrated circuit dies; and
a digital voltage offset controller (DVOC) configured to generate a digital offset voltage substantially equal to the difference between the digital reference voltage and the voltage detected by a selected one of the second voltage sensors, wherein the regulated output voltage is based on an unregulated input voltage, the analog sense voltage, and the digital offset voltage.
