An application of Beta wavelet networks to synthesize pass-high and pass-low wavelet filters is investigated in this work. A Beta wavelet network is constructed using a parametric function called Beta function in order to resolve some nonlinear approximation problem. We combine the filter design theory with wavelet network approximation to synthesize perfect filter reconstruction. The order fil...

An active RC filters with a 880 / 1760 MHz dual bandwidth tuning ability is present for 60 GHz unlicensed band applications. A third order Butterworth low-pass filter utilizes two Cherry-Hooper amplifiers to satisfy the very high bandwidth requirements of an amplifier. The low-pass filter is fabricated in 90nm standard CMOS process. Drawing 6.7 mW from 1.2 V power supply, the low frequency gain...

The proposed circuit is suitable for realize the proposed operation by using of two CDBA with the current processing application of filter design also we have driven the performance of CDBA. All-pass filter & Universa...

A new biquadratic universal filter configuration realizing second-order low-pass, band-pass, and high-pass fiters using single current conveyor is proposed. Using this configuration high-pass, low-pass and band-pass fiters can be realized with little modifications. The circuit employs a secondgeneration current conveyor (CCII+), and only four passive components. Since the current conveyor is a ...

We demonstrate integrated, mode-evolution-based, 1x2 port high-pass/low-pass filters in a silicon photonics platform that can simultaneously achieve broadband operation, single cutoff wavelength, and a record high filter roll-off of 2.5 dB/nm for the first time.

Introduction:Low-pass filters eliminate noise, and accordingly improve the quality of filtered back-projection (FBP) in the reconstruction of single photon emission computed tomography (SPECT) images. This study aimed at selection of an optimum low-pass filter for FBP reconstruction of SPECT images of small structures. Material and Methods:Sp...

This article presents a current-mode biquadratic filter and quadrature oscillator circuit based on current differencing transconductance amplifiers (CDTAs). The proposed does not require changing the topology. In addition to low-pass filter, high-pass band-pass sinusoidal signal, has pole frequency that can be controlled independently from quality factor, while oscillation non-interactively. im...
