摘要: The design of high-order log-domain filters can be easily accomplished by transposing already known linear-domain Gm-C filter topologies to their counterparts in the through employment a set complementary operators. To achieve topologies, multiple feedback approach is widely used due its accrued advantages. In this paper synthesis for development an nth-order multifunction comprising lowpass (LP), highpass (HP) and bandpass (BP) functions proposed. based on decomposition HP function follow-the-leader-feedback (FLF) topology. simple simultaneously achieves nearly all chief offers superior performance factors vis-a-vis ones recently reported. verify behavior topology, 5th-order was designed achieved simulated results theory.
