| Abstract | ||
| In this paper a proposed method to design electronic circuits by using software approach based on genetic algorithms is presented. The method is implemented to design low pass filter with a minimal knowledge about the design (the response of the filter and cutoff frequency). Butterworth filter type is chosen because of its smooth response. This method provides impressive results and the circuits obtained provide higher efficiency than the circuits which might be designed by the expert engineer. This method allows the topology, the component values, and the number of the component of the circuit to be evolved by using genetic algorithms (GAs) without human interference. Therefore, the proposed method can be expandied to be used with any analog (passive or active) circuit by making a few changes in the program steps (i.e. by changing the fitness function and improving the simulation of the circuits). MATLAB (Ver. 7) language is used in programming the genetic algorithm. The circuits created by genetic algorithms are built using EWB program to make sure that the obtained results are true and accurate. | ||
