Subhash Patel, Rajesh A. Thakker · Journal of Engineering Science and Technology Review · 2016
In this work, we have proposed modified PSO algorithm based optimizer for automatic circuit design.The performance of the modified PSO algorithm is compared with two other evolutionary algorithms namely ABC algorithm and standard PSO algorithm by designing two stage CMOS operational amplifier and bulk driven OTA in 130nm technology.The results show the robustness of the proposed algorithm.With modified PSO algorithm, the average design error for two stage op-amp is only 0.054% in contrast to 3.04% for standard PSO algorithm and 5.45% for ABC algorithm.For bulk driven OTA, average design error is 1.32% with MPSO compared to 4.70% with ABC algorithm and 5.63% with standard PSO algorithm.
