We present in this work is an analysis of the low temperature operation of Graded-Channel fully-depleted Silicon-On-Insulator (SOI) nMOSFETs for analog applications. This analysis is supported by a comparison between the results obtained by MEDICI numerical bidimensional simulations and measurements. The Graded-Channel transistor presents higher Early voltage and transconductance at 100 K if compared to the conventional fullydepleted SOI nMOSFET.
