The impact of variation also can be reduced by scaling the transistor gate. Dimensional variation is relatively constant on a given layer, so using a wider gate makes the variation a smaller percentage of the size, reducing its effect.

A design methodology to mitigate threshold voltage variation by delivering optimized and adaptive body bias in circuits with standard cells. Using two ...
Reducing Variability in Subthreshold Circuits by. Rajsaktish Sankaranarayanan ... • Development of a methodology to mitigate variation in subthreshold circuits.
Due to the independent nature of RDF variations it is possible to reduce their impact on circuit performance through averaging. Hence, we show how careful ...
In this paper, we present an analysis of subthreshold energy efficiency considering process variation, and propose methods to mitigate its impact. We show that, ...

On the one hand, driving CMOS circuits with the subthreshold leakage current can provide orders of magnitude power reduction over standard strong inversion ( ...
In this paper, a novel domino gate is proposed to decrease the process variability and leakage current with enhanced noise margin for wide fan-in OR logic.

Noise margin. Since VDD is reduced in subthreshold designs, the signal swing decreases. Therefore, the circuit is more sensitive to external noise.
Figure 3 shows that relative energy (Emin) and Vmin variations can be reduced dramatically by increasing path lengths in a circuit. Recent research has also ...
