  • This paper presents a new method of designing high-order CCII filter.The method is synthesizing input immittance of passive ladder network by CCII gyrators and realizing high-order current mode CCII nlter.The paper analyzes non-ideal character of CCII and gives out the compensation method. Compared with other similar circuits, the designed circuit using this method has simpler structure and fewer number of CCIIs. Design example of 6-th order Butterworth filter and its computer PSPICE imitation results before compensation and after compensation are also given.
