Section 7: Power Analysis:

When analyzing the power, we don't focus on the functionality, instead, we should notice the current I(vdd).

From the following HSPICE waveform, we can see that I_max= 45mA, so P=Vdd*I_max=112.5mW. This circuit was designed mainly using static CMOS design. If using dynamic CMOS design, the power consumption will become less. What I had in mind is making a comparison of dynamic and static CMOS design, due to the time limit, I did not finish the dynamic CMOS design part.
