STUDY OF DYNAMIC CURRENT MODE LOGIC VLSI CIRCUITS"

Abstract

This dissertation introduces a new reduced swing logic style called Dynamic Current Mode Logic (DyCML) that reduces both gate and interconnect power dissipation. DyCML circuits combine the advantages of MOS Current Mode Logic (MCML) circuits with those of dynamic logic families to achieve high performance at a low-supply voltage with low-power dissipation. Unlike Current Mode Logic (CML) circuits, DyCML gates do not have a static current source, which makes DyCML a good candidate for portable devices and battery-powered systems. Simulation and test results show that DyCML circuits are superior to other logic styles in terms of power and delay. The Cell Library is designed by using DyCML Logic in 211 CMOS technology. The results of CMOS Technology circuits and DyCML circuits show the differences in these two.
