Foundry service provider Jazz Semiconductor, a wholly owned subsidiary of Jazz Technologies, Inc., is offering new 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) last December 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, said the supplier. 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).

According to the developer, the new varactor model incorporates recent advances in MOS device physics and modeling and is based on the state-of-the-art surface potential based formulation. In addition, it provides MOS varactor specific gate current models and physical geometry and process parameter based parasitic modeling. Key device performances of capacitance and quality factor Q are accurately modeled over voltage, frequency, and geometry. The model contains physical process parameters, enabling simulation of changes in device characteristics associated with the changes in fabrication process. The scalability of the model enables simulation of critical trade-offs in VCO design such as gain and phase noise.

MOSVAR model libraries are currently available to Jazz customers through eBizz on the company’s website for its 0.13 and 0.18-micron processes.
