Active RC filters using Operational Transresistance Amplifiers

A new generalized universal filter configuration using the Operational Tran sresistance Amplifier is proposed. Twelve different filter circuits are der ived from the general configuration. The circuits are designed to provide L ow-pass, Band-pass, High-pass, All-pass and Notch responses through appropr iate choice of admittances. The feasibility of this configuration in operat ing at high frequencies is presented. A detailed analysis taking the effect of the finite transresistance gain into consideration is presented. Self-c ompensation that requires no additional elements of some of the proposed fi lters is presented. The effectiveness of the proposed configuration is demo nstrated by HSpice simulations.
