A way of generating millimeter wave I/Q signal using inductive resonator matched poly-phase filter is suggested. Normally the poly-phase filter generates quite accurate I/Q phase and magnitude but the loss of the filter is considerable due to series connection of passive RC components. This loss term directly increases system noise figure when the poly-phase filter is used in RF Front-end. The ...

The impact of electric car charging stations on power grid harmonics is growing as their existence continues to expand and creates harmonic distortion in the system. At same time, quality current voltage through process charge becomes inferior. Therefore, reduction output ripple factor (RF) mitigation input vital this situation. This paper presents design filter three kinds shunt passive filter...

This paper presents the development of highly integrated millimeter waves function in multilayer LTCC and Liquid Crystal Polymer technology. Both ceramic and organic technologies are candidate of choice for the 3D integration, following the system-on-package concept, of compact, low cost, millimeter-wave high data rate wireless systems. Compact and easy-to-design passive functions such as direc...

To measure nicotine personal exposure in our daily life, we have developed a determination method of personal exposure to nicotine. The method consisted of passive sampling of nicotine, simple solvent extraction and high performance liquid chromatography (HPLC) determination. The passive sampler was badge type and collection media was sodium bisulfate impregnated quartz fiber filter. The collec...

A current differencing transconductance amplifier (CDTA)-based multiple-input single-output (MISO) currentmode universal filter and a quadrature oscillator (QO) are presented in this paper. The same circuit is used in the filter and oscillator, which only consists of 2 CDTAs and 2 capacitors. The universal filter can realize low-pass, high-pass, band-pass, band-stop, and all-pass biquad filter ...

Krylov-subspace methods, such as the multistage Wiener filter and conjugate gradient method, are often used for reduced-dimension adaptive beamforming. These techniques do not, however, allow for steering vector mismatch, which is typically present in many applications of interest, including passive sonar. Here, we discuss recently proposed robust methods that do allow for steering vector misma...

The paper presents a novel modulated passive power filter scheme for nonlinear load bus voltage flicker control using an error-driven, error-scaled rule based controller for online voltage stabilization.

We present a novel multifunction inverse biquad configuration based on current feedback operational amplifiers (CFOAs) and grounded passive elements. The proposed scheme can be used to realize inverse lowpass, inverse bandpass and inverse highpass filter functions. The relevant coefficients of the inverse filters are orthogonal adjustable by independent passive elements. All the passive element...
