Standby power reduction using dynamic standby control with voltage keeper

This paper presents dynamic standby control (DSC) with voltage keeper for further standby power reduction. As compared to the reported DSC, the new modified DSC can be kept deeply cut-off with negative overdrive voltage as well. Besides, a bootstrapped voltage keeper directly recharges the boosted node of power gate, which prevents leakage current during the recharging period. However, total st...

Standby - Loss Elimination in Server Power Supply †

In a server power system, a standby converter is required in order to provide the standby output, monitor the system’s status, and communicate with the server power system. Since these functions are always required, losses from the standby converter are produced even though the system operates in normal mode. For these reasons, the losses deteriorate the total efficiency of the system. In this ...

Standby Voltage Scaling for Reduced Power

Lowering VDD during standby mode reduces power by decreasing both voltage and current. Measurements of a 0.13 m testchip 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 2X higher savings than optimal open-loop approaches without...

Standby Power Reduction Techniques for Asynchronous Circuits with Indeterminate Standby States

In the literature, some schemes were proposed to combine Multi-Threshold CMOS (MTCMOS) with asynchronous circuits to reduce standby power consumption. However, all of these can only be applied to asynchronous circuits in which the values of all signals can be determined in the standby state. As a result, their applications are limited. To solve this problem, this paper develops standby power re...
