Abstract
This paper presents a novel mixed-mode universal filter (UF) using digitally programmable second-generation current conveyor. The proposed single filter configuration is capable of realising all the standard filter functions in both inverting and non-inverting forms in all the four modes, namely voltage mode, current mode, trans-impedance mode and trans-admittance mode. The proposed configuration provides advantageous features, such as independently programmable filter parameters, easy cascadability and low-sensitivity figures. Workability of proposed circuit is verified by including the SPICE simulations.
