Abstract
A method and a circuit for adaptive regulation of body bias voltages controlling nmos and pmos transistors of an integrated circuit includes a digital circuit, a counter, a control unit and a charge pump. A first ring oscillator monitor measures a period duration of nmos transistors and a second ring oscillator monitor measures a period duration of pmos transistors. A first closed control loop adaptively regulates the performance cof the body bias controlled nmos transistors of the digital circuit by comparing the measured period duration of nmos dominated first ring oscillator monitor to a period duration of a reference clock and a second closed control loop adaptively regulating the performance cof the body bias controlled pmos transistors of the digital circuit by comparing the measured period duration of pmos dominated second ring oscillator monitor to the period duration of the reference clock.
