Development of wide-band geometry dependent RF planar spiral inductor SPICE model

Gadjeva E. D., Hristov M. H., Durev V. P.

International Journal of Microelectronics and Computer Science

2011

Vol. 2, nr 2

39-43

Parameterized wide-band geometry dependent SPICE models for oil-chip planar spiral inductors are developed in the paper. Model descriptions are presented in the form of PSpice model and in schematic view. The models are realized in the Cadence Capture and Cadence PSpice environment. The developed computer models can be used For adequate computer modeling and simulation of RF circuits. The geometry dependence of the model parameters allows geometry optimization and design automation of spiral inductors. The simulation results are compared to the measurement data for the model verification demonstrating the validity of the computer models.

Automated parameter extraction of geometry dependent RF planar inductor model

Durev V. P., Gadjeva E. D., Hristov M. H.

International Journal of Microelectronics and Computer Science

Vol. 1, nr 3

257-262

An approach is proposed in the present paper to parameter extraction of geometry dependent RF planar spiral inductor model. A direct extraction procedure is developed and realized in the Cadence PSpice and Cadence Probe environment based on the measured two-port S-parameters. To minimize the error for the full range of operation a Genetic Algorithm (GA) optimization procedure is applied in MATLAB environment. The approach is useful in RF model design, as the S-parameters can be easily measured for a given microelectronic technology. The proposed model extraction approach is characterized by a very good accuracy.
