A general synthesis method for the realisation of nth-order current transfer function is derived from signal-flow graph. From the proposed method, a novel configuration of nth-order current-mode universal filter using differential voltage current conveyors (DVCCs) and multiple outputs DVCC (MODVCC) is obtained. The number of active elements in the configuration is reduced to n+1, which is a significant reduction in comparison with the previously reported methods. The proposed circuits employ the features of multifunctional, smallest number elements, simple in structure, easy to be cascaded and convenient for integration. As examples, a biquadratic filter and other four different orders filters are realised in 0.18 mu m CMOS process. Simulation results are given to demonstrate the effectiveness of the schemes. The simulation results are found to be in good agreement with the theory.
