  This book focus on modeling and characterization of on-chip interconnects, inductors and transformers. Firstly, a fully scalable and SPICE-compatible interconnects model is established and is accurate over a wideband frequency range up to : Kai Kang, Wen-Yan Yin, Le-Wei Li. An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil around a core.. When the current flowing through an inductor changes, the time-varying magnetic field induces an electromotive force (e.m.f.) in the First production: Michael Faraday (). Inductors are often referred to as “AC resistors”. The ability to resist changes in current and store energy in its magnetic field account for the bulk of the useful properties of inductors. Current passing through an inductor will produce a magnetic field. A changing magnetic field induces a voltage which. Inductor design characteristics are defined in terms of various parameters. Inductor winding is made of a conductor material which may be a single round wire or a unique multi-stranded conductor known as Litz wire. Litz wire has the main advantage of reduced skin effect. Inductor design characteristics are defined in terms of various parameters which are discussed in this technical article.

Defining Characterization Characterization is the process by which the writer reveals the personality of a character. Characterization is revealed through direct characterization and indirect characterization. Direct Characterization tells the audience what the personality of the character is. Example: “The patient boy and quiet girl were both well mannered and did not disobey theirFile Size: 49KB. The smaller inductor values normally have a lower DCR, while the larger inductor values have a higher one. The DCR of an inductor is measured using DC current. DC current is fed into the inductor and then the resistance can be calculated from the voltage and current in the circuit using R=V/I.
