Abstract

As VLSI Industry is progressing towards integration of mixed analog-digital circuits for a complete system-onchip\nsolutions, automated analog circuit design methodologies are gaining attention. Automatic sizing of transistors has\nbecome an area of focus for the EDA industry. A lot of research effort has been put in by the designers for developing\ndifferent techniques for obtaining optimal circuit topologies and sizes of analog circuits satisfying desired specifications. But\nfrom past few years, evolutionary algorithm (EA) approaches have emerged as an excellent tool for solving optimization\nproblem in analog circuits. This paper presents a review of various EAs used for optimization. Firstly, Genetic algorithm\nalong with some discussion on its applications is presented. Also two other algorithms namely Particle Swarm Optimization\nand Ant Colony Optimization have been discussed. Besides discussion on these algorithms, various applications from\nliterature are given.
