We have developed a voltage control scheme to reduce control time using a delay monitor and step-by-step supply-voltage control. With this scheme, voltage control steps are adaptively controlled, and there are temporary overshoots in the reference voltage. Experimental results with a 65-nm CMOS device indicate that the adaptive voltage control steps successfully reduce the voltage control time by...
We have developed a circuit for determining an optimal supply voltage, VOPT, for which energy consumption will be minimized in devices suffering from high-leakage. This VOPT is determined on the basis of a trade-off between power consumption and operation time. Experimental results with a 90-nm CMOS device indicate that the proposed circuit successfully determines VOPT with high accuracy. VOPT operations...
We have developed a circuit for determining an optimal supply voltage, VOPT for which energy consumption in circuit operations will be minimized in devices suffering from high-leakage. This VOPT is determined on the basis of a trade-off between power consumption and delay time. Experimental results with a 90-nm CMOS device indicate that the proposed circuit successfully determines VOPT within 3% of...
