Original Abstract

In this paper, a novel topology using generalized current follower differential input transconductance amplifier (GCFDITA), which is suitable to realize several current-mode (CM) analog functions is presented. The topology is created using a single GCFDITA, a maximum of two grounded passive elements and can realize CM amplifier, integrator, first-order low-pass, high-pass, and all-pass filtering functions. The workability of one of the GCFDITA variants, namely the current inverter differential input transconductance amplifier (CIDITA) is proved by SPICE simulation results, based on the commercially available ICs OPA860 by Texas Instruments, and is in good accordance with theoretical predictions.
