Some results on two-section generalized FLF active filters

This paper presents some results on two-section generalized follow-the-leader-feedback (GFLF) active filters. The results are applicable to the design of geometrically symmetrical bandpass (BP) and band-reject (BR) elliptic-type fiters. An example illustrating sensitivity improve ment and lower pole-
