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?

Part 1) The clock in the image above has a pendulum of mass m = 1.19 kg that swings on the end of a rod that is l = 0.590 m long. The angular amplitude of the swing is α = 6.07 (which can be considered small). Assume the rod has a negligible mass. Determine the period of the pendulum in seconds. T = s Part 2) What is the maximum speed that the mass on the end of the pendulum has during its swing? v = m/s Part 3) The clock is powered by a 1.83 kg weight that falls slowly, taking one day to drop by 3.00 m. The falling weight supplies the energy to compensate for the energy lost through friction in the pendulum, ensuring the amplitude stays constant. Suppose that the weight reaches the floor and no-longer supplies energy to the clock. Estimate how long (in seconds) the pendulum will continue to swing (assuming the energy loss is constant with time). Tf = s
