1. An apparatus, comprising:
a voltage regulator circuit configured to generate a voltage level on a power supply node of a computer system using a source power supply;
a passive circuit element coupled to the voltage regulator circuit; and
a control circuit configured to:
determine, at a particular time, an updated value for the passive circuit element; and
adapt operation of the voltage regulator circuit based on a difference between an initial value for the passive circuit element and the updated value for the passive circuit element.
