WebIn order to address the subthreshold conduction phenomenon let us plot the IDS-VGS characteristics shown in Figure below. A closer inspection of the IDS-VGS curve shows that the current does not drop abruptly to '0' at VGS … 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… dr hayes tulsa chiropractic https://melissaurias.com
