SEOA based Optimal Design of Analog CMOS Amplifier Circuits

Abstract

This paper presents social emotional optimisation algorithm (SEOA) based optimal designs of two analogue CMOS amplifier circuits. In SEOA, human behaviour is organised for attaining superior position in society. The person with the topmost position in society provides the optimal solution in multi-dimensional search space in this virtual world. To earn the supreme position in society through the assistance and rivalry with others not only results in better exploration and exploitation of problem space but also ensures faster convergence to optimal solution. The transistors' sizes are optimised to minimise the total MOS occupied area with better performance parameters of the circuits. The simulation results prove that the efficiency of the proposed SEOA-based approach over DE, harmony search (HS), artificial bee colony (ABC) and PSO in terms of convergence speed, specifications of design parameters and yields the least MOS area with improved gain and lower power dissipation.
