Evolving Analog Circuits Based on Cell Arrays

Evolving circuits are based on the idea of evolutionary algorithms and reconfigurable hardware. It's valuable in aeronautics and astronautics. The principle of Evolving Analog Circuits are explained. The FPTA is an evolution -oriented reconfigurable cell architecture used for Evolving Analog Circuits. This paper analyzes the architecture of FPTA and introduces evolutionary algorithms, presents the method for Evolving Analog Circuits based on single chromosome evolutionary algorithm , The FPTA cell are converted into a model simulated by Pspice. The process of evolving analog circuits is controlled by VB and algorithm is realized also by it. The experiment of the band - pass filter circuits shows the function can be achieved using two new FPTA cells, the architecture of FPTA is feasible and the evolutionary method is valid.
