A state of the art Monte-Carlo simulator is applied to the investigation of the RF performance of Bulk and ultra-thin-body single-gate SOI MOSFETs designed according to the prescriptions of the 2005 ITRS Roadmap for analog and mixed signal applications. We provide an analysis of the signal-delay build-up along the channel and an investigation of the scaling properties of the parameters of the AC equivalent circuit, the transition frequency, and the 3dB bandwidth of the voltage gain in common-source configuration. A comparison with a standard drift diffusion approach is presented in order to discuss the main differences between the two transport models in terms of high-frequency AC analysis.

Abstract
A state of the art Monte-Carlo simulator is applied to the investigation of the RF performance of Bulk and ultra-thin-body single-gate SOI MOSFETs designed according to the prescriptions of the 2005 ITRS Roadmap for analog and mixed signal applications. We provide an analysis of the signal-delay build-up along the channel and an investigation of the scaling properties of the parameters of the AC equivalent circuit, the transition frequency, and the 3dB bandwidth of the voltage gain in common-source configuration. A comparison with a standard drift diffusion approach is presented in order to discuss the main differences between the two transport models in terms of high-frequency AC analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
