Differential evolution (DE) algorithm is a heuristic approach that gains more interest in today's research. It finds the true global minimum regardless of the initial parameter values, fast convergence, and using few control parameters. DE algorithm is a population based algorithm like genetic algorithm using similar operators; crossover, mutation and selection. This paper addresses the restrictive...
Negative bias temperature instability (NBTI) has been identified as a major and critical reliability issue for PMOS devices in nano-scale designs. It manifests as a negative threshold voltage shift, thereby degrading the performance of the PMOS devices over the lifetime of a circuit. In order to determine the quantitative impact of this phenomenon an accurate and tractable model is needed. In this...
