A new generalized universal filter configuration using the Operational Transresistance Amplifier is proposed. Twelve different filter circuits are derived from the general configuration. The circuits are designed to provide Low-pass, Band-pass, High-pass, All-pass and Notch responses through appropriate choice of admittances. The feasibility of this configuration in operating at high frequencies is presented. A detailed analysis taking the effect of the finite transresistance gain into consideration is presented. Self-compensation that requires no additional elements of some of the proposed filters is presented. The effectiveness of the proposed configuration is demonstrated by HSpice simulations.
