1-(50) Find: RG 15V Mr he - Yas , Im and the region of geration e km = 60 mA/v? V2v IMA 2002 and the region

Answer 1

45 RO RG 4 Ky = 60mAlue vt = 2V Ry=innar 15V You VID Ro= 2oon Vs. Iluso from the chruit Vs=0 due to is Some voltage gelte current Ten zo then drop a cemoss RG is also Zero thaf at at voltage ie VG Voans vyaNs VDS Vors as drain VDS E ves then We con say thal Vos > VGS VA from Here we can say that mosfet is in Saturation region region of operations = Saturation
