Question


I need help with the related problem.

EXAMPLE 8-18
17:53:16.
Solution
For a certain D-MOSFET, Ipss = 10 mA and VGS(off) = -8 V.
(a) Is this an n-channel or a p-channel?
(b) Calculate ID at VGs = -3 V.
(c) Calculate ID at VGs = +3 V.
(a) The device has a negative VGS(om); therefore, it is an n-channel MOSFET.

VGS
2)² = (10 MAX(1 - 3V)² = 3
mA)
VGS(off)
(b) ID = Ipss 1-
= IDss (1-
(c) I
= (10 mA)(1 - +3V)² =

= 18.9 mA
= 3.91 mA
