No matter whether the MOSFET is operated in linear or saturation region, bias condition dependence is found to be well described by a power function of voltage gain. By introducing a device's intrinsic 1 noise emf v nc(), which is independent from bias condition, and empirical parameter β,...

To activate this type of depletion type MOSFET, the gate voltage must be 0V and the drain current value is large so that the transistor will be in the active region. So, once more to turn on this MOSFET, +ve voltage is given at the source terminal. So with enough positive voltage& n...
Linear/Ohmic Region –It is the region where the current across the drain to source terminal enhances with the increment in the voltage across the drain to source path. When the MOSFET devices function in this linear region, they perform amplifier functionality. Let us now consider the switching...

Note the linear rise and fall edges of the switching waveforms which is due to the constant output current characteristic of the driver as opposed to the resistive output impedance of traditional MOSFET-based gate drivers. Sink and source currents of the driver are dependent upon the VDD value ...

Because the channel has a specific resistance, a voltage drop occurs along the channel, causing the potential of each channel point to gradually fall from the drain to the source area, and it is close to the drain region. The voltage VGD is the smallest, with a value of VGD=VGS-VDS, ...

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...
