This paper deals with the problem of the realization of low sensitivity narrow BP active filter implementing multiple critical pole approximation methods. Coupled active filter structures are also studied.

The position of a MCP (multiple critical pole) transfer function containing multiple poles is realized as FLF (Follow the Leader Feedback) and and remaining part as cascade. Further MCP transfer functions are combined with CBQ (Coupled Biquads), SCF (Shifted Companion Form), and LF (Leap Frog) structure.
