Unformatted text preview: D =5K, R S = 1K, V G =5, and V DD =15. V T =1 and C(w/L) =0.5 mA/V 2 Find the drain current and source and drain voltages. Solution: V S = I D * R S => Where I D = 0.5K (V GS- V T ) 2 if saturated. Also remember that V GS = V G- V S V S = 10.5 or 1.5 are the solutions to the quadratic equation. Only 1.5 is the logical solution. I D = 0.25(5-1.5-1) 2 = 1.56mA Thus: VD = 15 5K*1.56mA = 7.2 volts....
