Simulation and Analysis of Current Differencing Transconductance Amplifier (New Active Element)

In this paper a CMOS-based circuit for realization of high-performance current mode current differencing transconductance amplifier (CDTA) is demonstrated. This circuit provides the advantage of a wide frequency bandwidth and very small input terminal impedance. Some voltage and current mode applications using this element have already been reported in literature .It provides linear and non-linear application. Proposed model use the concept of bulk driven in CMOS and can be implemented by two current conveyors and one OTA with double current output. It has used voltage buffer compensation technic in feedback . Design in the CMOS technology has been verified via tanner tool simulation and for this implantation we are applying supply voltage of ±0.6V.
