SSRN Electronic Journal, 2006 In the following article the ideal band-pass filter is derived and explained in order to subsequently analyze the approximations by Baxter and King (1999) and Christiano and Fitzgerald (2003). It can be shown that the filters by Baxter and King and Christiano and Fitzgerald primarily differ in two assumptions, namely in the assumption about the ...

Implementation and analysis of tunable fractional-order band-pass filter of order 2α
, 2020This paper proposes a new design of a 2 α -order fractional-order band-pass filter with a tunability feature. The proposed filter is approximated with the second-order approximations of the Continued Fraction Expansion and the Matsuda.

Filter chain comprising at least two cascaded duals, each provided with two acoustically coupled resonators, only one of the two resonant frequencies of each of the duals falling within the filter pass band; the duals are convex at least on one side so as to render the acoustic coupling between the resonators so strong that the distance between the two

Electrically Triggered Tunable Terahertz Band-Pass Filter Based on VO2 Hybrid Metamaterial
IEEE Journal of Selected Topics in Quantum Electronics, 2019We demonstrate an electrically triggered tunable terahertz (THz) band-pass filter based on vanadium dioxide (VO2) embedded hybrid metamaterials. The unit cell of the filter consists of two cross resonators and a central bar.

0.5 V sixth-order Chebyshev band-pass filter based on multiple-input bulk-driven OTA
AEU - International Journal of Electronics and Communications, 2019This paper presents a low-voltage sixth-order Chebyshev band-pass filter based on multiple-input operational transconductance amplifier (MI-OTA). The used voltage supply is 0.5 V and the filter employs six MI-OTAs and six capacitors.
