A new capacitively coupled contactless conductivity detection (C(4)D) sensor with an improved simulated inductor is developed in this work. The improved simulated inductor is designed on the basis of the Riordan-type floating simulated inductor. With the improved simulated inductor, the negative influence of the coupling capacitances is overcome and the conductivity measurement is implemented b...

The improvement of a conventional Gyrator-C active inductor consisting of common-emitter configured and common-collector configured with resistance feedback is presented. The fixed passive resistor is replaced with tunable active resistor (TAR) to enhance the adjustability of the active inductor. Multi-regulated Cascode (MRC) circuit is applied to boost quality factor Q. Compared with the conve...

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...

Recent advances in semiconductor technology have greatly increased the performance and range of application of switched mode circuits. Periodic switching can give rise to acoustic noise [Y.-S. Lai, Random switching techniques for inverter control, Electronics Letters 33 (9) (1977) 747–749] or undesirable electromagnetic radiation. These problems can be reduced through the use of random switchin...

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.

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...
