Abstract: A new method of parameter optimization design is proposed by means of the in?depth study of the typical circuit of second⁃order active low⁃pass filter with multiple feedbacks. The second⁃order Butterworth active low⁃pass filter with multiple feedbacks was designed. The simulation analysis is performed for the filter by using the Multisim 13 circuit simulation software. The simulation results show that the active filter designed by the optimization design method has a good amplitude⁃frequency characteristic, and the system is stable, reliable and easy to implement. The precision of different components has different effects on filter features, so in practical application, it is advisable to rationally select ...
