Linear transformation transistor-only high-order current-mode filters are presented in this Letter. Based on the systematic design procedure, we can realize high-order current-mode filters employing switched-current technique efficiently. Only two kinds of switched-current basic cells are needed in our design to obtain simple architectures. The fifth-order Chebychev lowpass filter is designed to verify the proposed synthesis method. Simulation results that confirm the theoretical analysis are obtained.

A new current-mode (CM) multifunction filter with single input and three outputs (SITO) employing only three dual output current conveyors (DO-CCII) and four passive elements is presented. The proposed filter realizes three basic filter functions simultaneously all at high impedance outputs. No component matching is required and all the passive and active sensitivities are low.
