WebMay 22, 2024 · The voltage where the current begins to flow is called the threshold voltage and is usually denoted as \(V_{GS(th)}\), although it is sometimes shortened to \(V_{th}\) or just \(V_t\). Like both the JFET and DE-MOSFET, the E-MOSFET drain curve family exhibits three characteristic regions: the ohmic or triode region, the constant current or saturation … WebFor an n-channel MOSFET, the device operates in the first quadrant when a positive voltage is applied to the drain, as shown in figure 2. As the gate voltage (VG) increases above the threshold voltage (VTH), the MOSFET channel begins to conduct current. The amount of current it conducts depends on the on-resistance of the MOSFET, as defined by
