Abstract

The dual supply voltage (dual-VDD) scheme reduces the active power consumption without performance degradation by using two power supply rails. However, an increase in the delay due to the scaled-down supply voltage has made assigning the lower supply voltage (VDDL) more difficult in the conventional dual-VDD scheme. We propose a technique for the dual-VDD scheme employing the Active Body-biasing Control (ABC) on PD-SOI, which increases the number of VDDL-cells owing to lowered threshold voltage. Simulation results have shown our approach effectively reduces the power consumption even at low voltage operation.
