1. A circuit system comprising:
a first voltage regulator circuit that generates a first supply voltage for a first integrated circuit die based on a first control signal, wherein the first voltage regulator circuit generates a first feedback signal based on the first supply voltage;
a second voltage regulator circuit that generates a second supply voltage for a second integrated circuit die based on a second control signal, wherein the second voltage regulator circuit generates a second feedback signal based on the second supply voltage; and
a third voltage regulator circuit that generates the first control signal based on the first feedback signal and the second control signal based on the second feedback signal.
