A set of four coupled inductors is applied to a four-phase interleaved 1 kW bi-directional 14 V to 42 V dc/dc converter for automotive applications. The coupled-inductor structure is optimized, and the performance is examined through simulations and experimental measurements. Although coupled inductors offer bigger advantages in applications that require fast transient response, they also have ...

* D Abstract --Lossless broad-band microwave active inductors for generalpurpose use in microwave circuits are proposed and their characteristics are discussed. These active inductors are composed of a common-source cascode FET and a feedback FET, and operate in a wide frequency range with very low series resistance. A maximum Q factor of 65 is obtained. Theoretically, it can reach infinity. Fu...

In this paper, electromagnetic modeling of capacitors and inductors for printed electronic circuits is studied. Capacitors are successfully modeled by two-dimensional finite element software. Capacitive sensor for chemical detection is proposed and tested in water. Inductors are modeled by the integrating through the currents and obtained results have been compared with 3D finite element method...

The scope of this application note is to define the terminology associated with inductors and their applications. Some of these terms are listed in the component data sheets. Many terms go beyond the specification of inductors. These terms describe issues associated with inductor design and performance, magnetic materials and theory and applications. A thorough understanding of these terms and ...

A fully-integrated 4.3-7 GHz CMOS low-voltage wideband low-noise amplifier with helical inductors has been demonstrated in this paper. The CMOS LNA, operating at a supply voltage as low as 1 V, achieves a small signal gain of 14 dB and 3-dB bandwidth from 4.3 to 7 GHz. The minimum noise figure is 2.9 dB at 6 GHz. With the benefits of helical inductors, the total effective chip size is only 0.2 mm.

Possible configurations for microfabricated inductors are considered. Inductance can be set by adjusting permeability through control of anisotropy of a permalloy core or via a patterned quasi-distributed gap. A design methodology based on a simple model is proposed. A more accurate model and a numerical optimization are also developed. Design examples for 5and 10-MHz buck converters and 2.5-MH...
