A physically-based continuous analytical graded-channel SOI nMOSFET model for analog applications

In this work a continuous model for analog simulation of long-channel Graded-Channel (GC) Silicon-On-Insulator (SOI) nMOSFETs is presented. The model is based in a series association of two conventional fully-depleted (FD) SOI nMOSFETs with different characteristics, representing each part of the GC nMOSFET channel region. MEDICI numerical bidimensional simulations and experimental results are used to validate the proposed model.
