Subthreshold conduction中文

Web亞閾值電流,或稱亞閾值漏電流(英語:subthreshold leakage),是金屬氧化物半導體場效應管柵極電壓低於電晶體線性導通所需的閾值電壓、處於截止區(或稱亞閾值狀態)時, … WebThe subthreshold slope is a feature of a MOSFET's current–voltage characteristic. In the subthreshold region, the drain current behaviour – though being controlled by the gate terminal – is similar to the exponentially decreasing current of a forward biased diode. Therefore a plot of drain current versus gate voltage with drain, source, and bulk voltages …

WebVelocity-Saturation. From the physics of semiconductors it is proved that the velocity of charge carriers is linearly proportional to the electric field and the proportionality constant is called as mobility of carrier. Web15 Jun 2024 · The average subthreshold swing of 11.58 mV/dec is calculated from the I D-V GS curve for V DS = 0.5 V. The other advantage of GL-TFET is considerable suppression of the ambipolar conduction, which can be attributed to the device geometry and the fact that the source-sides of the channel are more affected by the gate than the drain-side of it. tall tripod iphone https://balzer-gmbh.com
