Combining dual-supply, dual-threshold and transistor sizing for power reduction

Multiple supply voltages, multiple transistor thresholds and transistor sizing could be used to reduce the power dissipation of digital blocks. This paper presents a framework for evaluating the effectiveness of each of these approaches independently and in conjunction with each other. Results show the advantages of multiple supply, transistor sizing, and multiple threshold can be compounded to maximize power reduction. The order of application of these techniques determines the final savings in active and leakage power. 1
