It appears certain that the process of cellular differentiation is an outcome of interactions between the cell nucleus and cell cytoplasm. Differentiation of embryonic amphibian ectoderm involves two fairly distinct phases: during the first short period an inductor (or some intrinsic factor, if an inductor is absent) determines the course of future differentiation in a multipotential cell; duri...
In this paper, a 5.2GHz low noise amplifier in 0.25um CMOS utilizing inter-stage matching is designed. Two realizations for a low value of inductor within the LNA are implemented. The measurement results are 7dB gain and 5.86dB noise figure is achieved for the on-chip inductor realization, and 8.3dB gain and 5.74dB noise figure is achieved for the bond-wire inductor realization.
This paper reports a single-wafer micromachined radiofrequency (RF) inductor that can be integrated in a conventional RFIC device. The inductor achieved a quality factor greater than 9 at 5Ghz and a self-resonance frequency well above 15 GHz. The inductor is tunable and the inductance variation is greater than 8%.
In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...
The input electrical impedance behaves as a capacitive when a piezoelectric transducer is excited near its resonance frequency. In order to increase the energy transmission efficiency, a series or parallel inductor should be used to compensate the capacitive impedance of the piezoelectric transducer. In this paper, the effect of the series matching inductor on the electromechanical characterist...
Our previous work has suggested that transferrin is an important serum component for differentiation of the kidney. In this study we have analysed more closely the response of cultured mouse embryonic kidney to exogenous transferrin and the dependence of kidney tubule induction on transferrin. Our results show that transferrin causes a dose-dependent increase in cell proliferation in the differ...
In this paper, a novel lossless floating inductor simulator with four resistors, a grounded capacitor and five two-terminal active components such as negative impedance converter, current follower and voltage follower, is presented. The capacitor in the floating inductor simulator is grounded, which provides suitability for integrated circuit fabrication. However, it needs resistive matching co...
Multilevel inverters with a common-ground structure and voltage step-up feature are beneficial for transformerless grid-connected photovoltaic applications. In this article, novel topology of such converters five-level output generation is presented. The proposed comprises an integrated switched-boost (SB) module dual T-type (D2T) cell constructed 10 power switches (six unidirectional two bidir...
An eddy current sensor with an ink-jet printed flexible inductor has been designed and fabricated. The inductor has been designed by means of software developed in-house. It has been fabricated by ink-jet printing with silver ink on a flexible substrate. The inductor is a part of the oscillator circuit whose oscillating frequency is measured by a microcontroller. The sensor characteristics have...
Inductor with gradual changed metal width and space by good design can get better Q factor than the inductor with fixed metal width and space. In this paper, a simple wide-band inductor model is presented considering both the increase of resistance and the decrease of inductance due to the skin and proximity effects. This model has been verified with simulation and the experimental results of s...
