Abstract
Disclosed is a circuit for adjusting a voltage supplied to an IC by a power supply circuit that produces a regulated-output voltage based on an output-control signal generated by a resistive voltage divider. The circuit includes a PVT detector configured to generate an interface control signal and an interface circuit (i) connected to PVT detector and to the resistive voltage divider and (ii) configured to adjust its resistance in response to the interface control signal. Adjusting the resistance of the interface circuit causes the voltage of the output-control signal to be adjusted, thus causing the power supply circuit to adjust the regulated output voltage.
