Abstract
This paper presents an energy-efficient standard-cell library design scheme: MEPNTC, targeting ultra-low-voltage near/sub- Vth operation. MEPNTC exploits an alternative logic style and inverse-narrow-width-effect (INWE) to extend the minimum energy point operation. A carefully engineered design style is presented to improve the PVT and glitch immunity of the cells while preserving balanced noise margins across a wider VDD range. The reduced parasitics and performance boost from both techniques have demonstrated up to 30 % -60 % of energy savings at 0.5V, typical near- Vth level for general-purpose hardware accelerator benchmarks (32-bit Booth Multiplier, 25- Tap FIR Filter, Forward Discrete Cosine Transform and JPEG Image Compression Units) compared to standard CMOS and INWE aware CMOS designs in 65-nm bulk CMOS technology.
