1.30P)a) Plot the channel formation of p-channel MOS-FET for linear and saturation pinch-off regime *). Explain how the channel changes with applied voltages. Show semiconductor structure, gate, drain, source and voltage polarities. b) Explain what happens if you apply voltages like i. Vg 0,Vs=0, iii. Vg >0, Vd 0,Vs=0, iii. Vg >0, Vd
