Abstract :This paper presents a high-performance current differencing transconductance amplifier insert ignore into journalissuearticles values(CDTA);, a recently reported active element, especially suitable for analog signal processing applications. A high linearity CMOS configuration for a CDTA is made up of high linearity input and output stages. The proposed CDTA provides high output impedance at port X and excellent input/output current tracking. A biquad filter circuit was chosen as an application example in order to demonstrate the performance of the CDTA. PSpice simulation results using a TSMC 0.35-m m CMOS process model were included to verify the expected values.
