Original Abstract

A new general configuration for realization of trans-admittance- and voltage-mode first-order all-pass filters based on differential-input buffered and transconductance amplifier (DBTA) is presented. The proposed generalized configuration is composed of single DBTA and four passive elements, however, the presented four different cases of all-pass filters, derived from the presented general circuit, employ only a single active and three passive elements. It is a first report of trans-admittance- and voltage-mode first-order all-pass filters at the same configuration in the literature. The DBTA is ideal for both modes first-order all-pass filter realizations because of its current and voltage outputs. The proposed circuits are cascadable and suitable for wideband applications. PSPICE simulation results are given to verify the theoretical analysis.
