A new depletion-mode MOSFET model is derived which includes the effects of the diffusion current along the channel and the actual band-bending at the semi-conductor surface. Because of the latter, a single drain current equation is obtained for the device operating in the linear region, ...

Based on threshold voltage — Uses the Shichman-Hodges equation to represent the device. This modeling approach, based on threshold voltage, has the benefits of simple parameterization and simple current-voltage expressions. However, these models have difficulty in accurately capturing transitions across...
I have a current sense IC powered directly from a battery. I want the current sense IC to be in the shutdown state when the 3.3V power supply is disabled...
Analysis of electron transport in the nano-scaled Si, SOI and III-V MOSFETs: Si/SiO 2 interface charges and quantum mechanical effects These investigation have been carried out using a selfconsistent solution of 1D Poisson-Schrdinger equation across the channel of conventional Si / SOI / III-...
Substitute the values in the above equation then we can get the Rin value. Rin = 2.5×1.5/2.5+1.5 Rin = 2.5 M Ohm x1.5M Ohm/4M Ohm Rin = 3.75/4 = 937.5 K Ohms Difference between BJT and MOSFET Amplifier Thedifference between the Mosfet amplifier vs transistor amplifieris listed below...

At this point we are ignoring channel-length modulation; consequently, as indicated by the equation, the drain current is not affected by the drain-to-source voltage. Now notice that both FETs have their sources tied to ground and that their gates are shorted together—in other words, both ...
