Jazz Semiconductor®, a developer of analog-intensive mixed-signal (AIMS) foundry solutions, announced the release of MOSVAR model libraries in its 0.13 and 0.18-micron AIMS technology platforms targeting wireless and other communication products. The new model improves simulation accuracy reducing product development time and is integrated as a standard component in Jazz's Design Enablement platform that also includes the previously announced Jazz Inductor Toolbox (JIT) and X-Sigma statistical simulation suite.

The MOSVAR model is an advanced surface potential-based MOS varactor model compatible with the PSP MOSFET model and was approved and released by the semiconductor industry Compact Model Council (CMC) in December 2007 as the first industry standard MOS varactor model. Jazz engineers contributed heavily to the model development, working closely with Arizona State University and other CMC member companies. The MOSVAR model provides critical advantages to the RF analog design space where circuit design requires accurate, scalable compact models for the active transistors and passive components in a given technology. This includes MOS varactors, which provide the critical frequency tuning for circuits such as voltage-controlled oscillators (VCOs).
