Question

In the following PMOS transistor, assume that VTH = -0.51 , \beta=800\mu A/V^2 and 0 . Find the current Ip and state whether it is in the saturated, triode, or cut-off region for the values of Rp 60kΩ and Rp 120kΩ . Assume that ID (VGS VTH) 2 if it is in the saturation region, and Ip = B((VGS – VTHVps DS if it is in the triode region.
