  • Abstract
    Lowering VDD during standby mode reduces power by decreasing both voltage and current. Measurements of a 0.13 μm test chip show that reducing VDD to near the point where state is lost gives the best power savings. We propose closed-loop voltage scaling that uses "canary" flip-flops for achieving these savings. This approach provides over 2× higher savings than optimal open-loop approaches without loss of state.
