Current differential trans-conductance amplifier (CDTA); analog signal processing/generating modules; current mode; trans-conductance (gm); bandwidth (BW); power consumption

In this paper a review on design perspective of current-mode current differential trans-conductance amplifier (CDTA) is presented for the state of the art analog signal processing/generating modules design as the main objective. The CDTA circuits are classified according to the active element used for the design with allrelated parameters taken into consideration. Likelihood implementations of different analog signal processing/generating modules are covered and a comparison of their main parameters trans-conductance, bandwidth, port impedances and power consumption is given. The feasibility of implementing with a lesser area is also considered from the VLSI design viewpoint. The review concludes with CDTA structures with the best possible parameters obtained and future possibilities.
