27 - Genetic algorithm for the Design of 4th order active Band Multiple Feed Back and Sallen key top

Asmae El Beqal, Bachir Benhala, Izeddine Zorkani Presented in: #ICMCS20 7th International Conference on Multimedia Computing and Systems Online, October 1-3, 2020 Presented by: Asmae El Beqal Faculty of Science Dhar el Mahraz, Fez, Morocco Abstract: In this paper we highlight the optimal design of an active fourth order band-pass filter for Radio Frequency IDentification (RFID) system reader to reject all signals outside the band (10-20) kHz and to amplify the low antenna signal with a center frequency of 15 kHz. The filter is designed to have a Butterworth response and the topologies that will be used to implement this filter are Multiple Feed-Back (MFB) and Sallen Key. The values of the passive components, forming the studied filter, are selected from manufactured series, this selection is one of the most crucial design steps in analog active filter design problems. As the number of possible combinations increases, it becomes infeasible to perform an exhaustive search for optimum component values. Thus, intelligent algorithms are required for a fast and optimum selection. In this study, the metaheuristic Genetic Algorithm (GA) is applied for the optimal sizing of the 4th order Band Pass Filter, SPICE simulations are used to validate the obtained results/performance"
