The motivation of this paper is to show systematic procedure how to design electronically reconfigurable first-order filtering section without change in network topology. It is verified that for different active elements matrix nodal methods can be directly used without any changes in the calculation algorithm. As a consequence this task does not represent problem and can be marked as educational...
This paper brings some practical examples how to create and utilize fractional-order two-terminal devices in analog filtering applications. Starting with desired decimal order of designed fractional-order element its passive circuit approximant is introduced and values of network components are calculated by using analytical formulas as well as Orcad Pspice optimizer. Then final device becomes a part...
