Mobile communication systems require a narrow-band BPF having low passband loss, high selectivity, small size and flat group delay. Such a filter response can be realized using filter with cross coupling between nonadjacent resonators. Normally this kind of filters is realized using waveguide cavities or dielectric resonators. This paper describes a method for CAD of cross-coupled BPF using min...

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...

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 ...

In this paper, a novel dual-band bandpass filter (BPF) based on a single short-ended dual-mode resonator (SEDMR) is presented. According to the voltage distribution of the resonator, two pairs of loaded open stubs, inside and outside of the resonator, are utilized to tune the center frequency and the external quality factor of the first passband respectively, while there is no influence on the ...

In this paper we will present an approach to realize FIR filters using Chebyshev Polynomials. Chebyshev polynomials play a vital role in antenna as well as in signal processing theory. The FIR filter design has also been disscussed previously [2-10], these papers discuss approximation methods, while the approach we will discuss in this paper gives exact design of FIR filter in Chebyshev sense. ...

A system-on-chip for the application of Electrocardiogram (ECG) monitoring and diagnostic is proposed in this paper, which includes reference circuit, instrumentation amplifier (IA), band-pass filter (BPF), amplifier stage and successive approximation register analog-to-digital converter (SAR-ADC). The Common-Mode Rejection Ratio (CMRR) of IA is greater than 132.87 dB, total gain of the AFE ach...

In this paper, we propose and research a novel miniaturized composite right/left handed transmission line (CRLH TL) cell based on revised complementary split ring resonators (CSRRs) for the first time. Novel CRLH TL cell is demonstrated with lower transmission and reflection zeros from electrical and electromagnetic (EM) simulation results. Negative refractive index of CRLH effect is successful...

This paper presents a novel compact suspended double side millimeter bandpass filter (BPF) with wide stopband using Suspended Compact Microstrip Resonant Cell (SCMRC). For SCMRC exhibits slow-wave band-stop characteristics, two distributed SCMRC structures are designed to achieve wide stopband characteristic. By applying SCMRC structure and double side design, this novel BPF is size reduced. Ba...
