Abstract: A device includes a temperature-variable voltage controller, in which the temperature-variable voltage controller comprises: a voltage regulator; a process monitor circuit coupled to the voltage regulator, in which the process monitor circuit includes a ring oscillator, and a frequency counter coupled to an output of the ring oscillator; and a temperature-variable current source coupled to the voltage regulator so that, during operation, the output voltage of the voltage regulator is compensated based on a change in temperature of the temperature-variable current source.
