Abstract : A system for synthesis of transfer functions of complex frequency having simple finite poles with finite Q and arbitrary zeros is proposed. The method uses generalized four parameter resonators connected in parallel and imbedded in an operational amplifier configuration such that lattice type two path transmission takes place. The resonators may be admittances of, say, discrete elements, but emphasis is placed on the case of two-port resonators characterized by their short cirucit transfer admittance. Active RC two-port resonators are developed using operational amplifiers. The two types required for general synthesis are sufficiently similar to permit building block type fabrication as integrated circuits using a single type of mask. The sensitivity of the resulting overall network to parameter errors and variations is calculated in general. The transmission sensitivity for a Butter-worth six-pole is calculated in detail as an example. Some aspects of the sensitivity of the active resonators are discussed. Experimental results verify that practical networks can be designed using the proposed system. (Author)
