A transformation method for equivalent infinite-gain op amp to unity-gain CCII networks

A method to obtain equivalent networks is proposed. This permits one to synthesize filters with unity-gain CCII/sup /spl plusmn// from well-known single infinite-gain op amp configurations. Current transmittance filters with high output impedance and voltage transmittance filters with high input impedance are obtained. These circuits have the same passive sensitivities as their op amp counterparts. So, many particular cases proposed in the literature can be understood from a unified viewpoint.
