WebAug 4, 2013 · Try and bias the MOSFET close to the bottom of your shown signal where the device is in its linear region where an input voltage gives a linear output. Difficult to explain without lots of pics. yes, I see it now. However, my confusion is the highlighted part in the picture. In the picture, it says that to maintain MOSFET in active region: WebThe operation of the enhancement-mode MOSFET, or e-MOSFET, can best be described using its I-V characteristics curves shown below. When the input voltage, ( V IN) to the gate of the transistor is zero, the MOSFET conducts virtually no current and the output voltage ( V OUT) is equal to the supply voltage V DD.So the MOSFET is “OFF” operating within its …

WebMay 22, 2024 · Two have been discussed: the constant current region is where the normal amplifiers and followers are biased, and breakdown is a region to be avoided due to potential damage. The third region is known as the ohmic region, or triode region. It occurs in the area where \ (V_ {DS}\) is less than the pinch-off voltage, \ (V_P\). WebApr 27, 2024 · Because of this, this region of operation is called the ohmic region, or the linear region, or the triode region. The terms “ohmic” or “linear” make sense to me because it is acting like a linear resistor at this point. The term triode is because the drain current of the FET depends on the drain voltage of the MOSFET, which is similar ...
