Design of odd-degree linear-phase sampled-data bandpass filters with equiripple amplitude response

This paper presents a novel approach for the design and synthesis of odd-degree sampled-data filters. Initially, an efficient iterative scheme is described for the construction of a class of selective linear-phase distributed bandpass filters with equiripple passband loss response. Then, the filter's transfer function is synthesized using classical distributed circuit networks. Finally, the equivalent switched-capacitor filter could be constructed. the resulting switched-capacitor networks are completely insensitive w.r.t. parasitic capacitances, as well as having low C_max/C_min Design tables and an illustrative example are also given.
