WebA MOSFET that normally turns ON without applying any gate voltage when you connect is known as a depletion mode MOSFET. In this MOSFET, the flow of current is from the drain terminal to the source. This type of MOSFET is also known as normally on the device. Once a voltage is applied at the gate terminal of the MOSFET, the drain to the source ... WebThis region of operation is commonly called the subthreshold region and plays an important role in determining switching characteristics of logic circuits. When an n-channel MOSFET is in weak inversion, the drain current is determined by diffusion of electrons from the source to the drain. This is because the drift current is negligibly small ...
