Applying inter reciprocity network theorem, a method was developed to implement the transform from RLC filter prototype circuits into active RC filter circuits, and finally into current mode filter based on current conveyor. The transfer functions and component sensitivities are common among them. It is effective in the processing of current mode analog signal, which is easy to implement.展开更多
