An introduction to Depletion-mode MOSFETs
aldinc.comdealing with depletion-mode MOSFETs will be straightforward. A few characteristics that may be a bit confusing are: 1. Drain saturation current - IDSS With an enhancement-mode MOSFET this is a leakage current. With a depletion-mode MOSFET it is the maximum limiting current that can flow between the drain and

5.11 THE JUNCTION FIELD-EFFECT TRANSISTOR (JFET)
global.oup.comThe description above clearly indicates that the JFET is a depletion-type device. Its char-acteristics should therefore be similar to those of the depletion-type MOSFET. This is true with a very important exception: While it is possible to operate the depletion-type MOSFET in the enhancement mode (by simply applying a positive v GS if the ...

www.nxp.comMOSFET. 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.

web.stanford.eduLimitations of Scaled MOSFET Effect of Reducing Channel Length: Drain Induced Barrier Lowering (DIBL) In devices with long channel lengths, the gate is completely responsible for depleting the semiconductor (QB). In very short channel devices, part of the depletion is accomplished by the drain and source bias
