Dynamic PD at nodes driven by sources.

For the CMOS circuit given below, estimate the total power dissipation.
Four inputs of this circuit, ABCD are stimulated repeatedly by the following
sequence of input vectors (one vector every 10ns):
1110, 1111, 1101, 1111, and 1100. Assume a supply of 3.3V,
an average leakage current of 10nA per gate; that each MOSFET has a
gate capacitance of 50fF, and this circuit drives an output load of 1pF.
What is the logic function implemented by this circuit?



For this circuit should we consider the CV2f power at the A,B,C and D nodes.

No becuase they are driven by the source and there is no power dissipation in any of the semiconductor devices. All the power from the source is transferred to the caps at these nodes and back from these nodes to the source.
