چکیده

The effective dielectric constants of a symmetric coupled microstrip line operating in the dominant mode are solved by using a closed-form formula of the asymptotic part of the impedance matrix elements. Using this asymptotic closedform solution, the finite upper limit for numerical integration in the evaluation of the impedance matrix elements is significantly reduced. This results in improved computational efficiency for determining the re of a coupled microstrip line while retaining a good accuracy compared to the conventional spectral domain approach (SDA).

Dispersion Characteristics of Open Microstrip Lines Using Closed-Form Asymptotic Extraction [Short P - Microwave Theory and Techniques, IEEE Transactions on

A full-wave spectral-domain method with an asymptotic extraction technique is formulated for multilayer microstrip lines. This formulation provides a simple closed-form representation of the asymptotic part of the impedance matrix by using Chebyshev polynomial basis functions with the square-root edge condition and the asymptotic behavior of the Green’s function. The formulation is applied to o...

An Efficient Technique for Substrate Coupling Parasitic Extraction with Application to RF/Microwave Spiral Inductors (RESEARCH NOTE)

This paper presents an efficient modeling method, based on the microstrip lines theory, for the coupling between a sub­strate backplane and a device contact. We derive simple closed-form formulas for rapid extraction of substrate parasitics. We use these formulas to model spiral inductors as important substrate-noise sources in mixed-signal systems. The proposed model is verified for the freque...
