Design the PMOS transistor network. Select the device sizes for both the NMOS and PMOS transistors to give a delay of approximately one-half the delay of the CMOS reference inverter (W/L=2/1 for NMOS, W/L=5/1 for PMOS). C is the same.

For the circuit in Figure 4, you can ignore body effect and channel length modulation. Equivalent resistance Req (W/L=1) of NMOS and PMOS transistors are Rn = 10 k and Rp = 25 k, respectively. (a) What function is implemented by this circuit? (b) Calculate the worst-case low-to-high propagation delay. Assume that all output capacitances are lumped together into a single load capacitance CL = 45fF. You may ignore all intermediate (internal) capacitances for this part. (c) Calculate the fastest high-to-low propagation delay. CL = 45fF. You may ignore all intermediate (internal) capacitances for this part. (d) What are the input patterns that give the worst-case tpHL and tpLH. State clearly what the initial input patterns are and which input(s) has to make a transition in order to achieve this maximum propagation delay. Consider the effect of the capacitances at the internal nodes for part (d).

(a) What is the logic function implemented by the pass transistor logic shown in figure. (b) Calculate the minimum and maximum propagation delay. All transistors have minimum length, L = 0.25 μm. Use Cg = 2 fF/μm, Cd = 1 fF/μm and W = 0.5 μm. Assume that the equivalent resistance of NMOS transistor of width W is 13kΩ; the equivalent resistance of PMOS transistor of width 2W is 13kΩ; the equivalent resistance of transmission gate with width of both NMOS and PMOS transistor W) is 13kΩ.
