A novel mixed-mode universal biquad employing plus current output DVCCs

摘要

This paper refers to a novel mixed-mode universal biquad employing plus current output differential voltage current conveyors with grounded passive components. The circuit performs mixed-mode operation with the selection of the input and output terminals, and it enables low-pass, band-pass, high-pass, band-stop and all-pass responses choosing suitable input signals. The circuit needs no component matching constraints for obtaining five basic circuit responses above, and can adjust orthogonally the characteristic parameters by the circuit component. Additionally, the circuit has extremely low sensitivities with respect to the circuit components. A circuit design is performed with PSPICE simulation in order to verify the workability of the circuit.
