Modeling of inductors and transformers

2001 IEEE MTT-S International Microwave Sympsoium Digest (Cat. No.01CH37157), 2002
This paper deals with modeling of spiral inductors and transformers. A lumped element approach is used to represent the spirals on a turn-by-turn basis. A previously reported approach for modeling of substrate eddy currents is employed and a new approach for modeling of current crowding effects is introduced.

Inductors and Transformers

2020
These take us into the realms of magnetics. Starting with the magnetic effect of an electric current, we derive an equation for the inductance of a solenoid and then to a consideration of B-H loops, magnetic domains, the magnetic circuit and the use of an air gap.

Micro-Inductors and Transformers

IEEE Translation Journal on Magnetics in Japan, 1994
Recently, many planar microdevices have been proposed, including planar bulk inductors, thin-film inductors, and thin-film transformers. In this paper, the high-frequency operation of thin-film microinductors and microtransformers prepared by photolithography techniques is investigated. Features such as the coil structure and resistivity, the structure

Stacked inductors and transformers in CMOS technology

IEEE Journal of Solid-State Circuits, 2001
A modification of stacked spiral inductors increases the self-resonance frequency by 100% with no additional processing steps, yielding values of 5 to 266 nH and self-resonance frequencies of 11.2 to 0.5 GHz. Closed-form expressions predicting the self-resonance frequency with less than 5% error have also been developed.

Stacked Inductors and Transformers

2003
Monolithic inductors have found extensive usage in RF CMOS circuits. Despite their relatively low quality factor, Q, such inductors still prove useful in providing gain with minimal voltage headroom and operating as resonators in oscillators. Monolithic transformers have also appeared in CMOS technology [8], allowing new circuit configurations.

Transformers, Inductors and Filters

Proceedings of the IRE, 1962
Transformers, inductors and filters have continually played important roles throughout the field of electronics. Relatively crude electromagnetic devices were employed in early telephone and radio communication systems and today their vastly improved descendants are still found in most electronic systems. The sizes of electronic power transformers have

ON THE TRANSFORMATION OF GROUNDED INDUCTORS TO FLOATING INDUCTORS USING OFA AND FCCII

Journal of Circuits, Systems and Computers, 2012
In a recent paper published in this journal, Soliman presented the methods of transformation of grounded inductors to floating inductors using operational floating amplifiers and floating second generation current conveyors. The purpose of this note is to bring on record the present author's earlier works on the same topic published about 24 years ...

ON THE TRANSFORMATION OF GROUNDED INDUCTORS TO FLOATING INDUCTORS USING OFA AND FCCII

Journal of Circuits, Systems and Computers, 2011
It is well known that a floating inductor circuit is realized from a grounded inductor circuit by replacing the operational amplifier by a floating operational transconductance amplifier. This idea is extended to transform current conveyor grounded inductors to floating inductors by replacing the current conveyor by the recently introduced floating ...

Capacitor, Inductor, and Transformer

1997
From the viewpoint of power handling capability, electronic circuits can roughly be placed into two groups: signal processing circuits and power processing circuits. In general, the power level processed by the signal processing circuits ranges from a fraction of 1 milliwatt to several milliwatts.
