PROJECT TITLE :

Energy Optimized Subthreshold VLSI Logic Family With Unbalanced Pull-Up/Down Network and Inverse Narrow-Width Techniques

ABSTRACT:

Ultralow-energy biomedical applications have urged the event of a subthreshold VLSI logic family in standard CMOS. This transient proposes an unbalanced pull-up/down network, together with an inverse narrow-width technique, to boost the operating speed of the individual logic cell. Effective logical efforts save both power and die area in the process of device sizing and topology optimization. 3 experimental 14-faucet 8-bit finite impulse response filters optimized for ultralow-voltage operation were fabricated in 0.eighteen- m CMOS. Measurements show that the optimized zero.45 and zero.half-dozen V libraries achieve minimum energy operations at one hundred kHz, with a figure-of-benefit of zero.365 (at 0.thirty one V) and zero.4632 (at 0.39 V), respectively. They correspond to 35.96% and 18.74% improvements, and the overall performances are well comparable with the cutting-edge.
