A high accurate and low-voltage analog CMOS current divider which operates with a single power supply voltage is designed in 0.18µm CMOS standard technology. The proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. The proposed divider is modeled with neural network while TLBO algorithm is used to optimize it. The proposed optimiza...

In this paper, a new N-way multi-frequency unequal split Wilkinson power divider (WPD) is proposed. The dividers are composed of multi-section transmission line transformers (TLT) and isolation resistors, which provide high isolation and very good input/output ports matching simultaneously at arbitrary design frequencies. To verify the validity of the design, several multi-frequency power divid...

En face autoradiography of the endothelium was used to quantify the distribution, area, and permeability of sites with enhanced permeability to 125I-low-density lipoprotein (125I-LDL) around the intercostal and celiac arteries and at the iliac bifurcation of normal rabbit aortas. The density of such sites was highest in the upper thoracic aorta and around the celiac and superior mesenteric bran...

Abstract In the design of a microstrip power divider, there are some important factors, including harmonic suppression, insertion loss, and size reduction, which affect quality final product. Thus improving each these factors contributes to more efficient design. this respect, hybrid technique reduce improve performance Wilkinson divider (WPD) is introduced in paper. The proposed method include...

The increasing computation requirements of modern computer applications have stimulated a large interest in developing extremely high-performance floating-point dividers. A variety of division algorithms are available, with SRT being utilized in many computer systems. A careful analysis of SRT divider topologies has demonstrated that a relatively simple divider designed in an aggressive circuit...

In this paper we consider a resonant injection-locked frequency divider which is of interest in electronics, and we investigate the frequency locking phenomenon when varying the amplitude and frequency of the injected signal. We study both analytically and numerically the structure of the Arnol′d tongues in the frequency-amplitude plane. In particular, we provide exact analytical formulae for t...

The design and simulation of a 1.35 GHz fully integrated CMOS frequency synthesizer for a double band receiver is presented. The proposed synthesizer is based in a wide-band PLL topology with a high reference frequency. This approach allows obtaining low phase noise, fast switching time, a low divider ratio and a reduction in the total chip area. Besides, the use of a novel charge-pump circuit ...
