Abstract

© 2017 IEEE. A novel subthreshold sizing strategy utilizing the Inverse Narrow Width Effect is demonstrated that has the largest range of propagation delays within the same cell footprint and lowest variability of any subthreshold sizing strategy thus far proposed. Simulation results and ring oscillators implemented in a commercial 65nm low power process confirm a propagation delay improvement of up to 1.95X over the standard superthreshold sizing strategy at 300mV and below. 32 bit multipliers are then synthesized and static timing analysis performed at several subthreshold voltage corners to illustrate applicability to real designs in conventional EDA design flows.
