An integrated circuit (IC) includes a first power supply node that is arranged to receive a first power supply signal. The IC also includes process detection circuits. Each process detection circuit provides a process detection output signal such that a value associated with the process detection output signal is a function of process variation at a location of the process detection circuit outputting the process detection signal. The IC also includes a processing unit that executes the processor-executable instructions to provide at least one voltage control signal, based, at least in part, on the process detection signals. The voltage control signal(s) include a first voltage control signal is associated with a target voltage for the first power supply signal.
