To turn on an N-channel Depletion-type MOSFET, to allow for maximum current flow from drain to source, the gate voltage should be set to 0V. When the gate voltage is at 0V, the transistor conducts the maximum amount of current and is in the active ON region.
22 lis 2022 · The only difference is whether the conductive channel is absent at zero gate voltage (enhancement-mode) or present at zero gate voltage (depletion-mode). You can even build a MOSFET that's somewhere between enhancement-mode and depletion-mode with a threshold voltage of exactly zero volts.
As its name suggests, the depletion type MOSFET (DE-MOSFET) was developed to be used in either or both the depletion and enhancement modes. Construction of Depletion Type MOSFET: Figure 13.67 shows the construction of an N-channel DE-MOSFET.
Depletion MOSFETs, unlike enhancement MOSFETs, are in an on-state even at 0 V of gate-to-source voltage (VGS). This feature makes them suitable for using as a constant current source as well as in other ways. This application note explains how depletion MOSFETs can be used in different applications.
