PSU’s Gildenblat Partners with Xpedion in PSP Model

Xpedion Design Systems Inc. has formed a partnership with Dr. Gennady Gildenblat, co-developer of the public domain PSP model. Gildenblat, professor of electrical engineering at the Pennsylvania State University (PSU), co-developed the PSP model with Philips. Gildenblat will work with Xpedion to provide PSP parameter extraction for Xpedion modeling services.

The Compact Model Council (CMC) selected the PSP model as the next generation industry standard CMOS transistor model, succeeding current industry standard BSIM3 and BSIM4 models.

“The PSP model significantly advances the state of the art in compact MOSFET modeling and is made possible by recently found practical solutions of several long-standing mathematical problems of compact modeling,” said Gildenblat. “Parameter extraction and training provided by Xpedion makes the model available for immediate engineering applications.”

The PSP model is suitable for RF applications because it incorporates all small-geometry and stress effects found in the best compact models, while being fully symmetrical and non-singular. The PSP also contains several features not available in other compact models, such as accurate and physical gate current description, output conductance of halo-doped devices, and the most complete noise model, accurately accounting for velocity saturation and channel-induced gate noise. PSP also offers an extensively verified unified non-quasi-static (NQS) model, which is available for accurate simulation of both RF and large-signal transient analysis and offers the most accurate reproduction of higher order harmonics in the drain current.
