Abstract

The lumped‐element electrical equivalent circuit of nichrome (NiCr) resistors is important for monolithic microwave integrated circuit (MMIC) design. This paper presents a methodology for the RF parameter extraction of thin‐film NiCr resistors fabricated on GaAs substrate. An algorithm based on DUT S parameters has been developed to extract the electrical parameters of the equivalent circuit up to 18 GHz for a large number of resistors of varying geometries and geometry‐scaleable curve‐fitted equations for the model parameters have been obtained. The computed S parameters, based on the extracted model parameters, agree reasonably well with the measured S parameters. Β© 2003 Wiley Periodicals, Inc.

A statistical description of the global performance of on-chip spiral inductors, based on extensive measurement is presented. These inductors were fabricated with different turn numbers or track lengths/track widths, but with the same spacing. From the S parameters measured using a de-embedding tech
