Determine the sizes of the NMOS and PMOS devices so that the network has approximately the same worst case tpHL and tpLH as an inverter (with an NMOS W/L = 1µm/0.25µm and PMOS W/L = 2µm/0.25µm.) which is driving an external capacitance of 20pF. Avoid increasing the area unnecessarily.

Draw the circuit diagram of a CMOS gate (showing all the transistors) which implements the logic function ((A + B + C) • D) + E b. (15pt) On the circuit diagram show the sizes of the NMOS and PMOS devices so that the network has approximately the same worst case tpHL and tpLH as an inverter (with an NMOS W = 5µm and PMOS W = 11µm.) which is driving an equal capacitance. Assume that self-capacitances are negligibly small compared to the load capacitance. Avoid increasing the area unnecessarily.

2-Consider the Circuit below a-)What is the logic function implemented by the CMOS transistor network? b-)Size the NMOS and PMOS devices so that the output resistance is the same as that of an inverter with an NMOS W/L = 4 and PMOS W/L = 8. C-) If P(A = 1) = 0.5, P(B = 1) = 0.2, P(C = 1) = 0.3 and P(D = 1) = 1, determine the power dissipation in the logic gate. Assume VDD=2.5V, Cout = 30 fF and fclk = 250 MHz. (To find the switching activity you must calculate the Pγ(0−1) = Pγ=1×Pγ=0 = Pγ=0×(1−Pγ=1)
