nth-order Current Mode Filter Based on MOCCCII-C

The paper presents a new general synthesis method for the nth order current mode filter based on MOCCCII(multiple outputs current controlled conveyors II).The method is based on the analytical solution of a single,nth-order generic filter transfer function and the generation of n number of realizable transfer functions using lossless integrators.The filter structure presented simply contains n active elements and n grounded capacitors.Various kinds of filters can be realized just by changing the amount and mode of joining external current signals without changing internal circuit structure and the amount of elements.So the circuit is convenient to be integrated.Pspice simulation for actual circuit is conducted,and the result shows that the presented circuit is valid and effective.
