The X-Parameter models are then available for use in EDA (Electronic Design Automation) software tools with X-parameter capabilities (such as Agilent Genesys, ADS, GoldenGate, and SystemVue plat- forms). The generated X-parameter models retain the accuracy of the compact version, while offering faster simulation speed. This service will unleash existing nonlinear device models from manufacturers and make them available for multiple EDA tools which will provide more flexi- bility and benefit to designers. Nonlinear X-parameters: x Provide mathematically correct extensions of S-parameters to large-signal conditions with fully nonlinear framework that provides both the magni- tude and phase of the distortion. x Cover both large-signal and small-signal conditions, and capture complete linear and nonlinear behavior at all loads. x Measure and characterize the amplitudes and relative phase of harmonics generated by components under large input power levels at all ports. Modelithics X-parameter Conversion Service x Generate non-linear X-Parameter models from existing compact models to make them available for multiple EDA tools. x Converted X-Parameter models offer the same accurate large signal predic- tion, such as power compression and load contours with much faster sim- ulation speed and better convergence characteristics. x Customer Input needed: access to non-linear model if not available on in- ternet or already in Modelithics NLT Library, plus details on desired model range of use in terms of frequency, operating bias and impedances. Comparison of the delivered power con- tours between the compact model with the X-parameter version shows good agreements The simulated output spectrum up to 3rd harmonics between the compact and X- parameter versions of the 100W LDMOS device is shown to present good match. “X-Parameters” is a registered trademark of Agilent Technolo- gies. The X-parameter format and underlying equations are open and documented.

An example X-parameter model generated from a compact version for a 100W LDMOS device is shown to demonstrate its performance. Ref. 120502 |
