This paper presents simple lumped element equivalent circuit for the coplanar waveguide (CPW) square spiral inductor. The circuit is based on physical modelling which takes into consideration the parasitic effects inherent in the CPW spiral inductor. The obtained scattering parameters are in good agreement with fullwave and quasi-static results available in the literature. Such a simple circuit...

Based on the fact that the real inductor and the real capacitor are fractional order in nature and the fractional calculus, the transfer function modeling and analysis of the open-loop Buck converter in a continuous conduction mode (CCM) operation are carried out in this paper. The fractional order small signal model and the corresponding equivalent circuit of the open-loop Buck converter in a ...

Cl ement Dept. of Electrical & Electronic Engineering, The Hong Kong University of Science & Technology Center for Integrated Systems, Stanford University, Stanford, CA 94305 Abstract| Recently, much studies have been done to include on-chip inductors fo...

This paper discusses the use of printed circuit board (PCB) integrated inductors for low power dc/dc buck converters. Coreless, magnetic plates and closed core structures are compared in terms of achievable inductance, power handling and efficiency in a footprint of 10 10mm. The magnetic layers consist of electroplated NiFe, so that the process is fully compatible with standard PCB process. Ana...

The main folder (name: non-linear inductor) includes four subfolders (Buck, Buck_Average, Behavior and Param_Mod), each folder contains one simulation project for the corresponding simulation circuit. The inductor data refers to a 77254A7 iron powder core (Kool Mu) characteristics, drawn from MAGNETICS data sheets.

This integrated single inductor dual-output boost DC/DC converter provides two independently regulated outputs with maximum efficiency at 83%. The converter operates in PWM and discontinuous mode at 500kHz using a 6.8uH inductor. Each output is time-multiplexed and regulated via current mode control. A drain-extended 0.13um technology allows backlight application up to 11V operation. The chip o...

In this project a number of circuits [1-4] with the characteristics of a passive inductor are to be assessed for their suitability for implementation in MMIC applications as a means of introducing a tuning function and as a replacement for the conventional passive inductor.

In 1982 Broniatowki [J. Appl. Phys. 56 (1982) 2907] estimated theoretically what is the change of capacitance as seen by a capacitance meter if an inductor is set in series with a DLTS sample. To the best of our knowledge, there have been no experimental studies on the inductor coupled in series with the sample to clarify in which way the inductor would actually change the DLTS spectra. In this...

the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...

The Low Noise Amplifier (LNA) is very much important in achieving good reception sensitivity in the wideband transceiver of Ultra Wide Band (UWB) architecture. In this paper, the LNA is designed for Multi Band-Orthogonal Frequency Division Multiplexing (MB-OFDM) receiver, which is used to transmit the information on 14 different sub bands of UWB with minimum of 528 MHz frequency in each band. T...
