Abstract
Measurement circuit components are included in an integrated circuit fabricated on a semiconductor substrate. These measurement circuits include registers that are connected to a voltage regulation circuit that provides the integrated circuit voltage source and to a power management circuit. These measurement circuits provide signals to control the voltage regulation circuit for adjusting the voltage output to the integrated circuit based upon a measurement values obtained on the semiconductor device. These measurements include temperature, IR drop at locations on the semiconductor substrate, along with the frequency response of integrated circuit.
