Abstract: An analog filter’s design used to need modification, computation and debugging in many times by manual work. An evolutionary hardware structure and multi-objective parallel evolvable design method for an analogue transconductance filter is presented. A parallel genetic algorithm with migration scheme based on penetration theory is applied, and parameters optimization of the transconductance filter is realized. Genetic operations to multi-objective parallel genetic algorithm are improved, and a multi-object fitness function for the filter parameter has been built. In the course of high Q value transconductance filter designing, structure of four-order bandpass transconductance filter is built by cascade method, which is able to meet performance request in its stop-band, passing band, transition band, and the practicality has been simulated and verified. Values of evolutionary parameters are in line with theoretical values exceedingly.
