In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

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...

A third-order Chebyshevlow-pass filter, using Gm-C structure, based on Nauta’s OTA, is presented. The filter is designed for 60GHz wireless communication using 65nm CMOS process and 1.2V power supply. The cutoff frequency of the filter is required to be tuned from 1GHz to 5GHz.UsingNauta’stransconductance characteristics, the filter can be operated at ultra-high frequency band and has a high li...

This paper provides a voltage mode (VM) multi input single output (MISO) universal filter with the help of voltage differencing inverting buffer amplifier (VDIBA). All the filter functions i.e., Low pass, band pass, band reject, high pass, and all pass filter functions can be realized without modifying the circuit configuration. The pole frequency can be independently tunable by its transconduc...

this paper presents a new design for a microstrip dual-band band-pass microstrip filter (bpf) with suitable isolation between two passbands. in this design, a basic structure is used to achieve a desirable frequency characteristic in the passband. in this regard, defected ground structure (dgs) is implemented to reach optimum parameters of the filter such as bandwidth, return loss, insertion lo...

This paper presents a universal current-controlled current-mode biquad filter employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs). The proposed filter employs only three MOCCCCTAs and two grounded capacitors. The proposed filter can simultaneously realize low pass (LP), band pass (BP), high pass (HP), band reject (BR) and all pass (AP) responses in current form ...

ABSTRACT:In this paper, an improved design of a tunable optical filter device made up of alternating layers of MgF2 and Ta2O5is proposed. Different configurations of this narrow band pass (NBP) optical filter are used for whole visible spectral range (400nm-700nm).We report on the calculated values of the design parameters, such as pass band wavelength, 3-dB bandwidth and quality factor for dif...
