Abstract Circuits operating in the subthreshold region are synonymous to low energy operation. However, the penalty in performance is colossal. In this paper, we investigate how designing in moderate inversion region recuperates some of that lost performance, while remaining very near to the minimum energy point. An power based minimum energy delay modeling that is continuous over the weak, moderate, and strong inversion regions is presented. The value of α is obtained through interpolation following EKV model. The effect of supply voltage and device sizing on the minimum energy and performance is determined. The proposed model is utilized to design a temperature to time generator at 32nm technology node as the application of the proposed model. The abstract goes here.

AbstractIn this paper, a review and analysis of different design techniques for (ultra) low-voltage integrated circuits (IC) are performed. This analysis shows that the most suitable design methods for low-voltage analog IC design in a standard CMOS process include techniques using bulk-driven MOS transistors, dynamic threshold MOS transistors and MOS transistors operating in weak or moderate inversion regions. The main advantage of such techniques is that there is no need for any modification of standard CMOS structure or process. Basic circuit building blocks like differential amplifiers or current mirrors designed using these approaches are able to operate with the power supply voltage of 600 mV (or even lower), which is the key feature towards integrated systems for modern portable applications.
