• How a P-Channel Enhancement -type MOSFET  Works

   

Apply a positive voltage VS to the source of a P-Channel Enhancement  -type MOSFET  and a negative voltage to the gate terminal of the  MOSFET to turn it on (the gate must be sufficiently more negative than the threshold voltage across the drain-source region) (VGDS). A current will be able to pass across the source-drain channel as a result of this.

The P-Channel Enhancement  -type MOSFET is completely functional and in the active 'ON' mode of operation when a sufficiently positive voltage, VS, is applied to the source and load, and a sufficient negative voltage is applied to the gate.

To turn off a P-channel enhancement type MOSFET.  there are 2 steps you can take. You can either cut off the bias positive voltage, VS, that powers the source. Or you can turn off the negative voltage going to the gate of the transistor.

• How  a P-Channel Depletion Type MOSFET Works

   

The gate voltage feeding the gate terminal should be 0V to turn on a P-Channel Depletion-Type MOSFET for maximum operation. The drain current is at its maximum magnitude when the gate voltage is 0V, and the transistor is in the active 'ON' zone of conduction.

There are two methods for turning off a P-channel MOSFET,  You can either turn off the bias positive voltage, VDD, which drives the drain, or you can leave it on. Alternatively, a negative voltage can be applied to the gate. The current is lowered when a negative voltage is applied to the gate. The current decreases as the gate voltage, VG, grows more negative until cutoff, at which point the MOSFET is in the 'OFF' state. A huge source-drain current is halted.
