Low voltage and low power inverter design

What is PVT variation tolerant design?

The authors provide process, supply voltage and temperature (PVT) variation-tolerant design techniques for inverter based circuits. They also discuss various analog design techniques for lower technology nodes and lower power supply, which can be used for designing high performance systems-on-chip.

Are low voltage circuits sensitive to threshold variations?

Low voltage circuits are therefore extremely sensitive to threshold variations, particularly those induced by random dopant fluctuations . The most basic question we must answer is how the minimum energy point (Emin) and the minimum energy supply voltage (Vmin, described by Equation 1) are affected by variation.

Can CMOS logic work at a low voltage?

Despite a non-ideal subthreshold swing, measurements of an inverter show that functionality can be achieved with a supply voltage of just 65 mV . It is clear that CMOS logic functions at extremely low voltages, but we must still consider the question of whether operation at these voltages is worthwhile.

Are there open research directions in the ultra-low voltage design space?

We conclude with a survey of open research directions in the ultra-low voltage design space. New classes of applications such as wireless sensor networks have dramatically different requirements from traditional integrated circuits (ICs) where performance (i.e., frequency) is the primary metric of interest.
