Subthreshold swing definition

Web15 Oct 2014 · The subthreshold swing definition describes an exponential behavior of the current as a function of voltage. The sign of the parameter should depend on the type of the device (n- or p-), so it's easier to just say that some voltage difference is required for a … Websubthreshold slope is the reciprocal of subthreshold swing.

WebThe subthreshold swing is poor unless the semiconductor-dielectric interface has low density of interface states such as carefully prepared Si-SiO 2 interface. The subthreshold swing is often degraded after a MOSFET is electrically stressed (see sidebar in Section 5) and new interface states are generated. Web1 Aug 2024 · In this context, the subthreshold swing, SS = dV g /dLn (I d ), V g being the gate voltage, is a key parameter measuring the turn-on capability of the MOSFET. Recently, it has been shown that the saturation of the subthreshold swing at cryogenic temperatures could originate from an exponential tail of states at the 2D subband edge [10], [11]. hanes men\\u0027s comfortwash https://ticoniq.com
