How to Calculate Subthreshold slope?
Subthreshold slope calculator uses subthreshold_slope = Threshold voltage*DIBL coefficient*ln(10) to calculate the Subthreshold slope, The Subthreshold slope formula is defined as 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. Subthreshold slope and is denoted by S symbol.
How to calculate Subthreshold slope using this online calculator? To use this online calculator for Subthreshold slope, enter Threshold voltage (V_{T}) and DIBL coefficient (η) and hit the calculate button. Here is how the Subthreshold slope calculation can be explained with given input values -> 11.51293 = 50*0.1*ln(10).
