Electrical Characteristics and Behavioral Model of Spiral Inductors on Gaas Substrate
نویسندگان
چکیده
Extensive experimental results for various square spiral inductors on GaAs substrate are presented in this paper. Through detailed studies of the inductances extracted from the de-embedded onchip measured S-parameters, the relationships between the electrical characteristics and the geometrical parameters of the spiral inductors are revealed. Based on the curve fitting technique, a behavioral model for spiral inductors is obtained and presented. Thus, the inductances of spiral inductors with an acceptable accuracy up to their first resonance frequencies are obtained.

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...
متن کاملPhysical 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...
متن کاملElectrical Characteristics of Planar Spiral Inductors
This paper describes two types of PEEC-based methods for the analysis of planar spiral inductors. One approach is a high-level distributed network method (DNM), while the second is based on a relatively simple equivalent SPICE circuit. The inductors are printed on lossless, grounded ceramic substrates and the metallization is assumed to have finite conductivity, but is infinitesimally thin, so ...
