Abstract: This paper deals with the proposal of an analog filter of the 3rd-order using Inverse-Follow-the-Leader-Feedback (IFLF) topology, which uses approximation of inverse Chebyshev. The filter is working in the current mode . The main advantage of this filter is an ability to electrically reconfigure its available transfer functions. The work focuses on the use of modern active elements. For design the filters was used transconductance amplifiers, second-generation current conveyors, current followers and current amplifiers . The function of the filter is verified by simulations in the OrCad PSpice software, with the ideal and behavior models of used active elements.
Keywords: active element; current conveyor; current mode; electronic reconfiguration; frequency filter; iFLF topology; operational transconductance amplifier; output summation; transfer function
