ABSTRACT:
A method for minimizing power consumption in a mobile device using cooperative adaptive voltage and threshold scaling is provided that includes receiving a supply voltage, a PMOS back bias voltage, and an NMOS back bias voltage. A clock signal is received. The clock signal is propagated through a timing comparison circuit. An output of the timing comparison circuit is examined. A determination is made regarding whether to request more power based on the output of the timing comparison circuit. A voltage control signal is sent to request more power when a determination is made to request more power based on the output of the timing comparison circuit.
