Calculation of electromagnetic parameters static and dynamic magnetically coupled inductors based on mathematical models their magnetic circuits is proposed. The inductance mutual such coils are determined using the geometric dimensions themselves, relative location, physical environment.

Fano resonance presents an asymmetric line shape formed by an interference of a continuum coupled with a discrete autoionized state. In this paper, we show several simple circuits for Fano resonances from the stable-input impedance mechanism, where the elements consisting of inductors and capacitors are formulated for various resonant modes, and the resistor represents the damping of the oscill...

--Coupled LC oscillators are known to provide good performance in terms of phase noise, signal amplitude, power consumption, and quadrature output signals. However, IQ amplitude and phase mismatches in these oscillators can be quite large due to the serious mismatch problem of large area inductors and varactors. A simple design modification of the coupled LC oscillators shows a significant impr...

On-chip inductors are critical for enabling portable power-efficient wireless communication systems. Existing on-chip spiral inductors based on conventional planar integrated-circuit fabrication technology suffer from substrate loss and parasitics, and have relatively large footprints. In this paper, we discuss the development of two types of on-chip three-dimensional (3-D) inductors—a vertical...

This paper presents a summary of several bandpass filters all consisting of resonators coupled only by capacitive coupling. The basic filter’s configuration with asymmetric inductors is explained in detail as well as its modifications with asymmetric capacitors. The filter’s design process is undemanding due to the filter’s simple configuration, while its compact size makes it suitable for inte...

In this paper, we propose a methodology for analyzing the near-field coupling between two surface mount device (SMD) inductors using 3-dimensional electromagnetic (3D-EM) model. To develop 3D-EM model, first constitute equivalent circuit of SMD inductor from measured impedance and derive loss tangent parameters. Secondly, damped harmonic oscillator model is introduced to extract effective perme...

Abstract: Bandpass filters play a significant role in wireless communication systems. Transmitted and received signals have to be filtered at a certain center frequency with a specific bandwidth. In designing of microstrip filters, the first step is to carry out an approximated calculation based on using of concentrated components like inductors and capacitors. After getting the specifications ...

The generalised steady-state analysis of the multi-phase interleaved boost converter with coupled inductors operated in continuous inductor current mode is addressed. The analytical expressions for efficiency, inductor and input currents, and output voltage are derived from the transformed average state–space model. Generalised expressions for the input and inductor current ripples and the outp...
