WebThe slope is m easured by plotting of the drain current in semi-logarithmic scale against V gs, which is linear in subthreshold region. The larger th e slope means the closer th e transistor s behaviour to an ideal switch. This paper focuses on the subthreshold leakage current reduction by application of two most popular leakage current WebUsing our positive stress voltage data, we calculated the sub-threshold slope variations and extracted the interface trap density (Dit). Surprisingly, we found that the subthreshold …

The 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 fixed will exhibit approximately log linear behaviour in this MOSFET operating regime. Its slope is the subthreshol… WebThe slope of this line is called ``subthreshold slope''. The inverse of this slope is usually referred to as ``subthreshold swing'' , given in units (mV/decade) and can be derived from …
