Q1. Consider the CMOS inverter of which the transistors have the following parameters: μnCox = 4μpCox = 160 μA/V2, ∣γ| = 0.5 V1/2, 2Φf = 0.5 V, λ = 0.001 V−1, Vtno = 0.6 V, Vtpo = −0.8 V, (W/L)n = 1 and (W/L)p = 4. The supply voltage VDD = 3.3 V. The capacitive load at the output node is 20 pF. The input voltage Vin is expected to be a perfect periodic square wave with full swing (low level : 0 V, high level: VDD). (a) Calculate tl, the time required for the output voltage Vout to change from 0 V to the threshold voltage of the inverter, using the average-current method. (b) Write the expression of calculation of t2, the time required for the output voltage Vout to change from 2.9 V to the 0.4 V, using the analytical method (integral). Then calculate t2 using the average-current method. (c) Determine the maximum frequency of the periodic square wave input so that the output signal will have a full swing in each cycle. (d) Calculate the peak value of in, the NMOS transistor current, during the transition, and its average value over a clock cycle T. (The average value here is not the same as the average-current in the "average-current method" for delay estimation) (e) If the capacitive load is now changed to be 250 pF, what can be done to make tl and t2 unchanged?

NMOS C-V curves A, B, and C are the measured C−V curves for a MOS capacitor. For this problem, assume that the poly-Si gate is degenerately doped and that the substrate is uniformly doped. (Recall that degenerately doped means the Fermi level coincides with either Ec or Ev. ) (a) Is the substrate doped with n-type or p-type? (b) Point out which of the C−V curves are measured in the low-frequency, high-frequency, or deepdepletion modes? (c) Under what experimental condition can we get the deep-depletion C−V curve? (d) What do we call V1 and V2? (e) What do we call regime 1 , regime 2 , and regime 3? (f) Is the poly-Si gate doped n+or p+? (Hint: You can tell from the polarity of Vfb. ) Sketch the energy band diagram when Vg = V2. (Assume there is no oxide charge.) (g) Sketch the energy band diagram for Vg = V1. (h) Determine Tox.
