Thermal Modeling of High-Frequency Inductors

Modeling of Spiral Inductors

This section explains overview of the on-chip inductors. Demand for on-chip inductors has been increasing especially for CMOS RF circuits. An on-chip inductor is a key component because its performance directly affects the circuit performance and the chip cost. The onchip inductors have been used, for example, as a matching network component, as baluns, and as an inductive load. The requirement...

Modeling Skin Effect in Inductors

Presents a technique for modeling skin effect losses in inductors. Includes a model written in Verilog-A as well as a model based on a new type of basic element named a frac-pole.

Physical Modeling of Spiral Inductors on Silicon

This paper presents a physical model for planar spiral inductors on silicon, which accounts for eddy current effect in the conductor, crossover capacitance between the spiral and center-tap, capacitance between the spiral and substrate, substrate ohmic loss, and substrate capacitance. The model has been confirmed with measured results of inductors having a wide range of layout and process param...

Time-Varying Modeling of Systematic Risk: using High-Frequency Characterization of Tehran Stock Exchange

We decompose time-varying beta for stock into beta for continuous systematic risk and beta for discontinuous systematic risk. Brownian motion is assumed as nature of price movements in our modeling. Our empirical research is based on high-frequency data for stocks from Tehran Stock Exchange. Our market portfolio experiences 136 days out of 243 trading days with jumps which is a considerable rat...
