drain current equationMOSFETWe present a rigorously derived current solution for undoped double-gate (DG) MOSFETs with two carriers, which is based on surface potentials. The third-order Newton–Raphson (NR) method is used to solve the surface-potential equations resulting from the application of ...

The gradient in the quasi-Fermi energy is responsible for the current flow; thus, both the drift and diffusion components are taken care of in this model. The surface potential model used is obtained by solving a pseudo-2D Poisson’s equation applied within the depletion layer depth along the...
Use Equation 1 to calculate the VOH as a result of an external pull-down resistor. VOH = VCCx × RPD / (RPD + 4kΩ) (1) 8.2.3 Application Curves VCCA = 1.8V VCCB = 3.3V Figure 8-2. Level-Translation of a 2.5MHz Signal 8.3 Power Supply Recommendations During operation, ensure ...
Furthermore, on-state resistance is not equal to the resistance expressed by the triode-region equation given above. The latter is the resistance of the MOSFET’s channel, whereas on-state resistance encompasses other sources of resistance—bond wires, the epitaxial layer, etc. Resistance characte...

A new approach for the modeling of the gate current source–drain partition is developed relying on a proper time response analysis of the MOSFET channel. The model enables to explain the non-uniformity along the channel and the gate length dependence of the gate current for MOSFETs with ultra...
For an electrolyte buffer solution, the λD is expressed by the following equation: (1)λD=14πlB∑iρizi where lB is the Bjerrum length = 0.7 nm, and ρi and zi are the density and valence, respectively, of ion species i. The screening directly depends on the Debye–Hückel length ...
