MOSFET transistor I-V characteristics
Depletion Mode NMOSFET • Depletion mode FETs have a channel implanted such that there is conduction with V GS=0 • The operation is the same as the enhancement mode FET, but the threshold voltage is shifted •Vt is negative for depletion NMOS, and positive for depletion PMOS VGS n+ n+ VS VDS n+ p

A depletion-type MOSFET can be made in the following manner: Starting with the basic structure of Figure 4, a moderate resistivity n-channel is diffused between the source and drain so that drain current can flow when the gate potential is at zero volts (Figure 7). In this manner, the MOSFET can be made to exhibit depletion characteristics.
