http://km2000.us/franklinduan/articles/long_channel_MOSFET_4.pdf WebThe preferable way is to reduce the subthreshold swing. S can be reduced by reducing η. That can be done by increasing Coxe (see Eq. 7.2), i., using a thinner Tox , and by decreasing Cdep, i., increasing Wdep. 1 An additional way to reduce S, and therefore to reduce Ioff , is to operate the transistors at significantly lower than the room temperature. rail strike 7th january https://mikebolton.net

WebIt is shown by calculations and verified by experiments that the subthreshold swing varies with gate bias and exhibits a global minimum. The gate-source voltage for which minimum subthreshold swing is reached, is linearly related to the voltage at which moderate inversion starts. Influence of oxide thickness and temperature is investigated. Websubthreshold swing – or the sharpness of the ON/OFF switching. A big part of advanced IC technology development is to achieve the best gate control of the channel to minimize the subthreshold swing degradation from the ideal value. However, it is generally accepted that the best one can do is to reach the theoretical limit of 60 mV/dec @300 K.
