[1] The amount of subthreshold conduction in a transistor is set by its threshold voltage , which is the minimum gate voltage required to switch the device between on and off states. However, as the drain current in a MOS device varies exponentially with gate voltage, the conduction does not immediately become zero when the threshold voltage is ...
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 subthreshold slope. The subthreshold slope is also the reciprocal value of the subthreshold swing S s-th which is usually given as: [1]
[1] [10] Since 2005, the clock frequency has stagnated at 4 GHz, and the power consumption per CPU at 100 W TDP. The breakdown of Dennard scaling and resulting inability to increase clock frequencies significantly has caused most CPU manufacturers to focus on multicore processors as an alternative way to improve performance.

Junction temperature, short for transistor junction temperature, [1] is the highest operating temperature of the actual semiconductor in an electronic device. In operation, it is higher than case temperature and the temperature of the part's exterior.
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.
The basic TFET structure is similar to a MOSFET except that the source and drain terminals of a TFET are doped of opposite types (see figure). A common TFET device structure consists of a P-I-N ( p-type , intrinsic , n-type ) junction, in which the electrostatic potential of the intrinsic region is controlled by a gate terminal.
The EKV Mosfet model is a mathematical model of metal-oxide semiconductor field-effect transistors which is intended for circuit simulation and analog circuit design. [1] It was developed in the Swiss EPFL by Christian C. Enz, François Krummenacher and Eric A. Vittoz (hence the initials EKV) around 1995 based in part on work they had done in ...
