New op-amp circuits realizations using genetic algorithm

Genetic algorithm (GA) applications in analog design circuits play an important role with promising results. This algorithm is utilized to generate equivalent circuits for the well-known Tow-Thomas (TT) filter which is the most commonly used active circuit. This paper introduces a proposed methodology based on the genetic algorithm and the symbolic representation to generate equivalent op-amp configurations for well-known filters. This methodology is applied to the TT filter to generate 168 different configurations. The generated realizations are simulated using PSPICE simulation and the simulation results showed that some generated circuits have better performance compared with the original configuration.
