Power Dissipation Analysis and Optimization of Deep Submicron CMOS Digital Circuits

This paper introduces a simple analytical model for estimating standby and switching power dissipation in deep submicron CMOS digital circuits. The model is based on Berkeley Short-Channel IGFET model and fits HSPICE simulation results well. Static and dynamic power analysis for various threshold voltages is addressed. A design methodology to minimize the power-delay product by selecting the lower and upper bounds of the supply and threshold voltages is presented. The effects of the supply voltage, the threshold voltage, and ?> , which reflects the drain induced barrier lowing, are also addressed.
