(a) Calculate the voltage at which vO = vI for a CMOS inverter with Kn = Kp. (Hint: Always remember that iDN = iDP.) Use VDD = 2.5 V, VTN = 0.6 V, VTP = -0.6 V. (b) What is the current IDD from the power supply for vO = VI if (W/L)N = 2/1? (c) Repeat the calculation in (a) for a CMOS inverter with Kn = 2.5Kp. (d) What is the current IDD from the power supply for vO = VI if (W/L)N = 2/1?
