An apparatus and a method to adjust a source voltage based on an operating voltage response are provided. The apparatus includes a circuit configured to change state from a first state to a second state comprising receiving an operating voltage from a power source through a power distribution network. The apparatus further includes a sensor configured to measure an operating voltage response to the circuit changing state to receiving the operating voltage. The apparatus further includes a control circuit configured to adjust a source voltage at the power source based on the operating voltage response measured by the sensor. The method includes changing a state to receiving an operating voltage from a power source through a power distribution network, measuring an operating voltage response to the changing state to receiving the operating voltage, and adjusting the source voltage at the power source based on the measured operating voltage response.
