“…Simulations are performed using an analytical model [14, 15] for frequencies from 0.5 to 15 GHz. Calculations consider the FMR of nanowires involved in the formula of relative permeability of the substrate, as explained in next section, dielectric losses of alumina membrane depending of porosity, the coupling between strips of the meander inductor, and the skin depth effect from aluminum electrodes.…”

“…Recently, Yupapin et al [13,14] have shown the promising idea that the nonlinear effects of light in fiber optic of microring resonators. In this work, the simple system of the attosecond pulse generation using the integrated optic devices known as the multistage microring resonators is proposed [15]. The large bandwidth signal can be generated within the microring device by using a light pulse input into the nonlinear microring resonator and filter referred to as an add/drop filter the characteristics of complementary ring resonator modeling [16].…”

We fabricated a planar inductor onto a substrate made of high aspect ratio ferromagnetic nickel nanowires in a self‐supported alumina nanoporous membrane. We observe a simultaneous increase of the inductance value and the quality factor up to 7 GHz, thanks to the large amount of ferromagnetic material and the nanoscale of the wires limiting conducting losses. Our device shows the largest increase reported in the literature for such ferromagnetic inductors: +30% for the inductance value and +23% for the quality factor. Even more, this technology offers great advantages as an easy integration in miniaturized topologies and its tunability to a magnetic field to broaden the desired frequency range. Our analytical model predicts that the increase of quality factor can be maximized up to 35% by an optimization of the pores filling. © 2012 Wiley Periodicals, Inc.

This paper presents a technique for low noise figure reduction of low-noise amplifier (LNA). The proposed LNA is designed in a source degeneration technique that offers lower noise figure. The resistance of the on-chip inductor is reduced by using multilayer that significantly reduces the thermal noise due to spiral inductor. Also, using spiral inductor as a gate inductor reduces the effect of the input parasitic capacitance on the noise figure and provides a good matching at the input and output of the LNA. The results of the LNA using multilayer on-chip inductor compared will off-chip inductor have been illustrated. It shows that the proposed technique reduces significantly the noise figure and improves the matching. The proposed LNA is designed in 0.13 μm process with 1.3 V supply voltage and simulated using Advanced Design System (ADS) software. The simulation results show that the LNA is unconditionally stable and provides a forward gain of 11.087 dB at operating frequency of 15 GHz with 1.784 dB noise figure and input and output impedance matching of -17.93 dB, and -10.04 dB.

“…The approaches, such as using high resistivity substrate and high conductive metal layers, thick dielectric layer or selectively etching off substrates, stacking metal layers [7,8], and even differentially driven inductors, have been reported [9,10]. However, no systematic study on the performance trend of spiral inductors with temperature has been reported in the literature, except in [11].…”
