Abstract :A novel circuit sizing technique with improved accuracy and efficiency is proposed to resolve the sizing issues in the analog circuit design. The grey wolf optimization insert ignore into journalissuearticles values(GWO); algorithm has the total number of iterations divided equally for exploration and exploitation, overlooking the impact of balance between these two phases, aimed for the convergence at a globally optimal solution. An enhanced version of a typical GWO algorithm termed as enhanced grey wolf optimization insert ignore into journalissuearticles values(EGWO); algorithm is presented with improved exploration ability and is successfully applied in analog circuit design. A set of 23 classical benchmark functions is evaluated and the outcomes are compared with recent state of the art. A conventional two-stage CMOS operational amplifier circuit realized in UMC 180nm CMOS technology is used as a benchmark to validate the efficiency and accuracy of the proposed optimization technique. A statistical study is also conducted over the final solution to investigate the exploration ability of the algorithm proving it to be one of the robust and reliable techniques.
