DXCCTA: A new active element

A new active element, namely, dual-X current conveyor transconductance amplifier (DXCCTA) has been proposed in this paper. The proposed DXCCTA has an important property of inbuilt tuning and shows very good performance with regards to bandwidth, dynamic range and power consumption. In order to verify the workability of DXCCTA, one application as current-mode multifunction filter (CM-MF) is given. The low-pass, band-pass and high-pass responses are available simultaneously from the proposed circuit of current-mode multifunction filter without any circuit modification. HSPICE simulation results confirm the proposed theory of DXCCTA and its application.
