Universal Filters Using Operational Transresistance Amplifiers

摘要

A new generalized universal filter using the Operational Transresistance Amplifier is proposed. Two different configurations leading to twelve different universal filters are presented. All reported filters have independent control on the bandwidth, quality factor and gain. Detailed analysis taking the effect of the finite transresistance gain into consideration is given. Self compensation that requires no additional elements of some of the proposed circuits is presented. Simulations are in good agreement with the theoretical analysis.
