2001 Simulation of Semiconductor Processes and Devices 2001  
This imposes stringent requirements on compact models used in circuit simulation: not only currents and charges, but also noise, power gain, impedances, and harmonic distortion must be modelled accurately  ...  In this paper several of these issues will be addressed with the help of Philips' new public-domain compact MOS model, MOS Model 1 1.  ...  High-frequency distortion and non-quasi-static effects Finally we discuss the impact of NQS effects on RF distortion. In Fig. 14, 1 GHz distortion data for a 2pm n-channel transistor are shown.  ...

DC and Large-Signal Microwave MOSFET Model Applicable to Partially-Depleted, Body-Contacted SOI Technology

Darren R. Burke, Majid El Kaamouchi, Danielle Vanhoenacker-Janvier, Thomas J. Brazi
2007 IEEE MTT-S International Microwave Symposium Digest  
A new compact DC and large-signal physics-based non-quasi-static (NQS) MOSFET model is proposed, suitable for partially-depleted body-tied silicon-on-insulator (SOI) MOSFETs.  ...  NQS distributed channel behaviour is accounted for by using a segmented channel model allowing the model in principle to operate up to high mm-wave frequencies.  ...  ACKNOWLEDGEMENT The authors wish to acknowledge the supported of Science Foundation Ireland.

An investigation on RF CMOS stability related to bias and scaling

Jiong-Guang Su, Shyh-Chyi Wong, Chun-Yen Chang
2002 Solid-State Electronics  
Due to the fact that CMOS device has continuously shrunk in size, a detailed discussion of the effect of MOSFETs dimension on stability is included.  ...  In recent times, CMOS devices have played an increasing important role in the area of RF-ICs to implement part of the high-frequency circuits.  ...  The channel charging resistance that represents the non-quasi-static effect of channel charges would increase the k-factor as observed in Eq. (6).  ...

2003 IBM Journal of Research and Development  
The rapidly expanding telecommunications market has led to a need for advanced rf integrated circuits.  ...  Complex rf-and mixed-signal system-on-chip designs require accurate prediction early in the design schedule, and time-to-market pressures dictate that design iterations be kept to a minimum.  ...  Acknowledgments The authors wish to acknowledge the many individuals in IBM who contributed to the SiGe program and are responsible for the current position of SiGe technology in the marketplace.  ...
