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.
Every time the temperature sensing network determines that a rise above the specified junction temperature (), is imminent, measures such as clock gating, clock stretching, clock speed reduction and others (commonly referred to as thermal throttling) are applied to prevent the temperature to raise further. If the applied mechanisms are not ...
In semiconductor electronics, Dennard scaling, also known as MOSFET scaling, is a scaling law which states roughly that, as transistors get smaller, their power density stays constant, so that the power use stays in proportion with area; both voltage and current scale (downward) with length.
Where is the thermal conductivity, is the density of the medium, is the specific heat, =, the thermal diffusivity and is the rate of heat generation per unit volume. Heat diffuses from the source following the above equation and solution in an homogeneous medium follows a Gaussian distribution.
If the MOSFET is an n-channel or nMOS FET, then the source and drain are n+ regions and the body is a p region. If the MOSFET is a p-channel or pMOS FET, then the source and drain are p+ regions and the body is a n region. The source is so named because it is the source of the charge carriers (electrons for n-channel, holes for p-channel) that ...
The MOSFET (metal–oxide–semiconductor field-effect transistor) utilizes an insulator (typically SiO 2) between the gate and the body. This is by far the most common type of FET. The DGMOSFET (dual-gate MOSFET) or DGMOS, a MOSFET with two insulated gates. The IGBT (insulated-gate bipolar transistor) is a device for power control. It has a ...
Subthreshold leakage in an nFET. Subthreshold conduction or subthreshold leakage or subthreshold drain current is the current between the source and drain of a MOSFET when the transistor is in subthreshold region, or weak-inversion region, that is, for gate-to-source voltages below the threshold voltage.
