Modeling low frequency noise in PDSOI MOSFETs for analog and RF applications

Abstract

In this paper we present the modeling of low frequency in 0.18um PDSOI technology. The two main noise sources, 1/f and excess noise due to shot noise have been discussed. It has been shown that accurate modeling of the body voltage, impact ionization, diode currents and 1/f noise characteristics is essential to incorporate the correct bias and frequency dependence of this excess noise component. Model to hardware correlation for body-contacted and floating body device is also shown to match well with the industry standard BSIMSOI 4.3 model. ©2010 IEEE.
