MOSFET is a three-terminal, voltage controlled, high input impedance, and unipolar device which are essential components in different electronic circuits. Generally, these devices are classified into two types enhancementMosfet& depletion Mosfet based on whether they have channels in their default conditi...
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...
