Multiobjective Differential Evolution algorithm using crowding distance for the optimal design of analog circuits

Abstract

This paper details the Multiobjective Differential Evolution algorithm (MODE) using crowding distance for the sizing of analog circuits. MODE is used to compute the Pareto front of a biobjective optimization problem, namely maximizing the high current cut-off frequency and minimizing the parasitic input resistance of a second generation current conveyor. To highlight performances of MODE, comparisons with the non-sorting genetic algorithm (NSGA-II) were performed. These comparisons show that MODE outperforms NSGA-II in terms of quality of the optimal solutions, diversity of those solutions along the Pareto front, and computing time.
