Abstract
A voltage regulator circuit included in a computer system may generate a voltage level on a power supply signal using a source power supply signal and based initial values of one or more operation parameters derived from wafer-level test data. One or more operation characteristics of the voltage regulator circuit may be sampled, by a measurement circuit, at multiple time points to generated measurement data. A control circuit may adapt operation of the voltage regulator circuit based on the measurement data.
