An application of NSGA-II for parameter optimization in the design of a CMOS voltage reference circuit is presented in this paper. It is difficult by manual work to design the optimal parameters and get the best performances of TC, LS and PSRR with power and time constrains. In this paper, NSGA-II, a multi-objective optimization algorithm, is used to optimize the parameters. Considering the characteristics of CMOS voltage reference circuit, the initial population generation scheme based on manual optimal solution and the special fitness function are proposed to increase the convergence speed and optimization efficiency. Simulation results show that LS, TC and power are improved by 32.18%, 12.5% and 19.53%, respectively, compared with the manual solution.
