摘要：This work attempts to reduce component count in Low, High, and All Pass active Filters. It also uses a lower order filter to achieve same results as higher order ones in terms of the frequency response. The optimizers used are Nelder-Mead, GA and PSO. The filters are transformed into small signal analysis while nodal analysis is used to translate a circuit to matrix form. Three different examples are presented to illustrate the effectiveness of the approach. Results have revealed that with a computer program, a lower order operational amplifier filter can be used to achieve same results as a higher order one. Also, PSO can achieve the best results as regard frequency response for the three examples, followed by GA while Nelder-Mead has the worst result
