The power dissipation of a digital circuit is minimized by simultaneous control of power supply voltage and body bias. The technique minimizes power dissipation for varying processing rates through dynamic adjustment of V/sub dd/ and V/sub tb/. A 16b MAC operates at 166 kHz and 14 nW at 175 mV V/sub dd/. A ring oscillator operates at 0.1 V.
