Summary: Simple modifications are proposed for the normal as well as the inverse Chebyshev filter (ICF) for facilitating doubly terminated LC ladder realization, and consequently cascaded active-RC implementations, for all specifications. The resulting filters are compared with two recently proposed solutions, as well as the competing conventional ones in terms of cutoff slope and the Q of the complex poles. The advantages of the modified filters are discussed.
