Abstract

An approach to deriving current-mode continuous-time filter based on third-generation current conveyor(CCIII) from voltage-mode active RC filter was presented.The filter can realize second-order low-pass,high-pass and band-pass filtering functions.The proposed circuits have simple structure,low passive/active sensitivity.In addition,active parameters would have no effect on pole frequency W0,which remain constant,when passive parameters were defined.HSPICE simulation demonstrated the feasibility of the proposed circuits.
