4. Consider the following structure of dynamic MOS logic circuits. Assume that the minimum size of
NMOS is 3.5 units (n = 3.5) and PMOS is 4.5 units (p = 4.5) with channel length of 0.15 µm (L = 0.15
µm). Determine the minimal channel width (in µm) of each of the transistor below (Qp, QA, QB, QC, and
Qe), so that the logic is operational. (20%)
