WebSep 8, 2016 · Controlling self heating and floating body effect could be useful to have better subthreshold behavior in MOSFETs. Fig. 9 shows the comparison of subthreshold swing for MB-MOSFET and C-MOSFET devices. In SOI-MOSFETs, body potential increases due to the floating body effect. So, threshold voltage would be reduced. The floating body effect is the effect of dependence of the body potential of a transistor realized by the silicon on insulator (SOI) technology on the history of its biasing and the carrier recombination processes. The transistor's body forms a capacitor against the insulated substrate. The charge accumulates on this capacitor and may cause adverse effects, for example, opening of parasitic transistors in the structure and causing off-state leakages, resulting in higher current consumpti…
