3. Threshold voltage Vth = 0.7 V, nox = 200 A/V, pox = 200 A/V, W/L = 5. Ignore channel length modulation = 0 and body effect. VDD = 1.8V. (a) In Fig. 3(a), draw the voltage transfer curve of Vout when Vin is DC from 0V to 1.8V. Specify the operating point Vout and Vin at cut-off, linear, saturation region (b) In Fig. 3(b), draw the VTC. (c) In Fig. 3(c), draw the VTC. VDD VDD 20k92 -OV Vino out Vin -V 20 (a) (b) Fig. 3 VDD J out Vin NMOS -OV out PMOS (c) 4. When body effect must be taken into account, and using VSB=1V to simply your calculation. Redraw the problem 3 (a), (b), (c). V th=V tho+7 [2, +V st +VSB - 20, 20, = 0.7V, y = 0.41/2
