Abstract :
In this paper a new method for the design automation of the folded-cascode operational amplifier is proposed. In this method the design of the amplifier is introduced as a multiobjective optimization strategy and a non-dominated sorting genetic algorithm-II (NSGA-II) is utilized for solving the optimization problem in CMOS technology. The proposed method is a model free algorithm and doesn´t need the accurate analytic formulas of the amplifier. It provides a set of solutions rather than a single solution and reveals the trade-offs between the conflicting objectives.
