Pass Transistor Logic

Consider the circuit of Figure 6.12. Assume the inverter switches ideally at VDD/2, neglect body effect, channel length modulation and all parasitic capacitance throughout this problem.
a. What is the logic function performed by this circuit?
b. Explain why this circuit has non-zero static dissipation.
c. Using only just 1 transistor, design a fix so that there will not be any static power dissipation. Explain how you chose the size of the transistor.
d. Implement the same circuit using transmission gates.
e. Replace the pass-transistor network in Figure 6.12 with a pass transistor network that computes the following function: x = ABC at the node x. Assume you have the true and complementary versions of the three inputs A, B and C.
