Abstract
In this study, a novel active signal processing block called Fully Differential Voltage Differencing Current Controlled Current Conveyor (FD-VDCCC) is proposed. The input and the output stages of FD-VDCCC consist of a fully differential operational transconductance amplifier and a current controlled differential voltage current conveyor, respectively. The FD-VDCCC can be adjusted by bias currents. The proposed active element has not only various differential voltage and current input terminals but also various voltage and current output terminals. Hence, the proposed active element complies with current mode or mixed mode circuit designs. In the study, in order to demonstrate the functionality of the considered structure, FD-VDCCC based current controlled universal filter is proposed. The study also contains the CMOS realization of FD-VDCCC and SPICE simulation results obtained with 180 nm TSMC CMOS technology parameters for the proposed FD-VDCCC and universal filter structures.
