WebDec 29, 2024 · ZeroFunGame. 93. 5. TL;DR Summary. I'm trying to understand the difference between subthreshold slope and transconductance. The subthreshold slope is the change in drain current / change in gate voltage. The transconductance of a MOSFET is proportional to the drain current / VGS - Vth. It would seem the subthreshold slope is … WebJan 26, 2024 · Subthreshold region of MOSFET operation refers to the weak inversion regime where off-current is not ideally zero. Under weak inversion, current flow is dominated by the diffusion mechanism due to the lateral gradient of carrier concentration. Further note that there is no lateral electric field in the channel region and hence the channel surface … WebA novel experimental technique, based on the double-gate operation, is proposed for extracting the back interface trap density of the fully depleted SOI MOSFET. The method … いらすとやさん 考える人
