This paper investigates the influence of substrate bias of junctionless (JL) and Inversion-Mode (IM) MuGFETs such as a variation of threshold voltage. The JL MuGFET has a similar response to positive substrate bias as an IM MuGFET. However, narrow JL MuGFETs are far more sensitive to negative substrate bias than IM MuGFET.
