PVT Variability Check on UCM Architectures at Extreme Temperature-Process Changes

Abstract

The UCM (universal compressor-based multiplier) architecture promises to provide faster multiplication operation in supply voltage as low as 0.6 V. The basic component of UCM architecture is a universal compressor architecture that replaces the conventional Wallace tree algorithm. To extend the work further, in this chapter, a detailed PVT (process-voltage-temperature) analysis is performed using Cadence Virtuoso 90nm technology. The analysis shows that the delay of the UCM has reduced more significantly than the Wallace tree algorithm at extreme process, voltage, and temperature.
