A new conventional mobility formula is advised to overcome the enigmas of the known formula. It is made possible to extract all device parameters including the series resistance for each device, and the formula is helpful in deriving an I– V formula over the entire linear region of MOSFETs. ...
linear region1/f noiseunified modelThis paper presents results of low frequency noise measurements for a Dual-Gate MOSFET (DGMOSFET) in linear region. DGMOSFET working conditions are chosen in order to set both inner transistors in linear regime. Results are discussed with the use of the ...
For low resistances, the resistance would not be a function of current, except to for the nonlinearity of the FET (there will always be some nonlinearity, even in the "linear" region). You can use a FET as a VCR, but each unit will require a different Vgs to get a given value of ...
When a MOSFET operates as a switch it's jumping between cutoff and "linear". M2 is no different in this regard. Could it be that you have mistook the "linear" region to be the same thing in a MOSFET as in a BJT? It's really messed up and back-asswards terminology between BJTs ...
What is the current of a MOSFET in the triode region? In the triode (or linear) regime, the drain current of a MOSFET is: ID = (W/L) × Cox × µN × (Vgs - (Vds/2) - VT) × Vds where: W/L –Width to length ratio of the MOSFET's channel; Cox –Capacitance of the ...

This section briefly describes each region of operation and its boundary limits. In complementary to this short section, Infineon also provides a comprehensive application note regarding this topic - Linear Mode Operation and Safe Operating Di...
MOSFET can be used as a small-signal linear amplifier within many applications. Usually, in the amplifier circuits, field-effect transistors work within the saturation region. So in this region, the flow of current does not depend on drain voltage (VD) but the current is the main function of...
DRIVING HEXFET®S FROM LINEAR CIRCUITS The complementary source follower configuration of Figure 9 can also be used in linear applications to improve drive capability from an opamp or other analog source. Most operational amplifiers have a very limited slew rate, in the order of few V/microsec....
