In this work, we are interesting in the analysis and the design of an ultra wideband (UWB) band pass filter with improved upper stop band performances, using microstrip lines. The design of the UWB band pass filter is based on the use of stepped-impedance low pass filter and high pass filter; whereas the simulation of its frequency response ([S]) is done using MATPAR software and it is based on...

In this paper, a channel drop ring resonator filter based on two dimensional photonic crystal is proposed which is suitable for all optical communication systems. The multilayer of silicon rods in the center of resonant ring enables one to adjust resonant wavelength of the ring and enhance power coupling efficiency between ring and waveguide. Refractive index and radius of multilayer rods insid...

The performance of a high pass filter (HPF) and a band pass filter (BPF) with and without defected ground structure (DGS) was analyzed in this specific work. The Defected ground structure includes rectangular and circular etched shapes in ground plane. Calculation and comparison of the response of both filters was done separately. Parameters of the proposed configuration were calculated at the ...

this paper presents a novel microstrip low-pass filter with good performance. a complete detailed theoretical analysis for the proposed filter is given using equivalent circuit models. the proposed filter applying multiple cascaded modified radial stubs resonators provides a sharp cut off frequency response that has a 185 db/ghz roll off rate. also, u-shaped attenuators provide a wide stop-band...

A new three-input and single-output current-mode biquad filter using one plus-type inverting second-generation current conveyors (ICCIIs), two grounded capacitors and two resistors is presented. This filter can simultaneously realize five generic low-pass, band-pass, high-pass, band-reject and all-pass filtering signals. H-Spice simulations with 0.35μm process are used to validate filter feasib...

In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...

A new current-mode multifunction filter using minimum number of passive elements is proposed. The proposed filter has single-input and four high-impedance outputs. It uses four passive elements (two capacitors and two resistors) and four dual output second generation current conveyors. Each output provides a different filter response, namely, low-pass, high-pass, band-pass and band-reject. The ...

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
