Abstract :
The aim of the paper is to present a fuzzy method for the optimization of the CMOS operational amplifier design. Our method uses fuzzy systems or fuzzy sets in all stages involved in the optimization process. In order to reduce the time spent for circuit performance evaluation, we use fuzzy system to model each circuit performance. The optimization problem formulation is accomplished in a flexible manner using fuzzy sets to define fuzzy optimization objectives. We use qualitative design knowledge to modify the design parameters in each iteration. This is done using a fuzzy system for each parameter. After introducing our fuzzy optimization method we design a basic two-stage CMOS operational amplifier
