Abstract
New circuit topologies are proposed for obtaining lowpass all-pole and elliptic filters of any order. The derived circuits retain the attractive features of the leapfrog circuits and in addition they retain the topological equivalence with the prototype LC ladders. The formation of transmission zeros is straightforward. An example of 7 th-order elliptic filter including a sensitivity study is given
