Abstract

Abstract:

Because of non-convergence and other problems the IC robustness design can not be achieved by only relying on the EDA simulation. A method is presented that uses the Response surface methodology (RSM) combined with EDA simulation designs, optimizes circuits for robustness, and is applied to the design of band-gap reference circuit. Through Hspice simulation and experimental design, the model of 3 objects and 4 parameters is built using 27 experiments. Based on the model the circuit is optimized for robustness. The optimized parameter sets satisfying the design targets make the circuit output more insensitive to the temperature variation.

Key words: robust optimization design, response surface methodology, design of experiment
