A Circuit Approach for CMOS VLSI Circuit Leakage Power Reduction
Abstract: Despite the fact that scaling CMOS technology boosted speed, leakage currents always remained an issue. The issue has gotten worse as the scaling has gone into the UDSM (ultra-deep-submicron) range. In order for the circuit to function effectively, these unwanted leakage currents must be reduced to a minimum. It is challenging to create these leakage-free nano-scale CMOS circuits. In this work, the issue of leakage power is addressed, which occurs …
