WebFloating body SOI MOSFET is exposed to hysteresis in transient response, which is referred as history effect. High speed switching circuits are mostly affected by this … WebMay 1, 2024 · The kink effect is a well-known floating-body mechanism in partially-depleted (PD) SOI MOSFETs: majority carriers, generated by impact ionization and stored within the body, increase the body potential and lower the threshold voltage [1], [2], [3], [4], [5]. More carriers are available for impact ionization and further increase the body potential.

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… WebThe effect of the scaling down on the electrical performance of trench power MOSFET structures is investigated in this work by means of numerical simulation tools. Layout dimensions of trench power MOSFETs have been continuously reduced in order to decrease the specific on-resistance, maintaining equal vertical dimensions.
