Abstract :
It is essential to control supply voltage VDD and threshold voltage VTH for low power, high-speed CMOS design. In this paper, it is shown that these two parameters can be controlled by designers as objectives of design optimization to find better trade-offs between power and speed. Quantitative analysis of trade-offs between power and speed is presented. Some of the popular circuit techniques and design examples to control VDD and VTH are introduced. A simple theory to compute optimum multiple VDD and VTH values is described. Scaling scenarios of variable and/or multiple VDD and VTH values is discussed to show future technology directions.
