In this work, an ultra-wideband (UWB) optical bandpass filter (BPF) based on nanoplasmonic structure is designed and thoroughly analyzed. The proposed BPF encompasses asymmetric metal-insulator-metal (MIM) slot waveguide that incorporates a gap-coupled series parallel square ring resonators (SRRs). characteristic parameters of the MIM are analyzed with full-wave analysis conformal mapping techn...

As we know that the conventional filter synthesis procedure is adequate only for the relatively narrow band filters and is not suitable for the Wideband and Ultra wideband filters .Therefore we are intend to design a Ultra Wideband filter. In this study a compact Ultra Wide Band pass filter consisting of quarter wave resonant conductor like micro strip lines is proposed to design. We have to in...

Targeting the range defined by FCC (Federal Communication Commission) in 2002 for ultra-passband bandpass filters, i.e., 3.1 to 10.6 GHz, this article presents a simple compact multipoles ultra-wideband filter (range starting from 2.9 GHz and end at 11.5 with central frequency 7.2 GHz) using parallel coupled microstrip line multimode resonator controllable double narrow notched bands 3.5 7.5 em...

Using the finite element method (FEM) in two dimensions and the CST MICROWAVE STUDIO (CST MWS) Transient Solver, the electromagnetic (EM) analysis and the design of a novel compact ultra wideband (UWB) bandpass filter using rectangular coaxial cables with square inner conductors, convenient for high power applications, are presented. The design of the UWB BP filter is based on the use of impeda...

This paper reports an Ultra wideband pass filter with a center frequency of 3.96 GHz and 3 dB bandwidth of 1584 MHz. The filter design is based on transversal signal interference principle implemented by means of transmission lines.The features of this filter include low insertion loss, sharp rejection along with simple design approach. Also, comparison of simulation and measured filter paramet...

An ultra-low power OTA-C bandpass filter is presented in this paper. An 1-150 Hz 4-th order OTC-C bandpass filter is design which is suitable for ECG application. A subthreshold region OTA is designed with current cancellation technology to achieve a very small transconductance. The OTA-C filter is design with TSMC 0.18μm CMOS process. The MIM capacitor is used in this design. The supply of the...
