Abstract

In this paper, we investigate the Optimizing Operational Transconductance Amplifiers through the constrained Particle Swarm Optimization (PSO). We optimize the folded cascode OTA performances, namely the static gain, the transition frequency, the common mode rejection ratio (CMRR) and the positive power-supply rejection ratio (PSRR). A comparaison with two other optimization methods shows good reached performances. The optimized circuit is used to design a 2^nd order Biquad Gm-C low-pass filter.
