    1. The problem statement, all variables and given/known data
    It given the expression [​IMG]. how to construct the complex CMOS gate by looking at the expression.

    2. Relevant equations

    3. The attempt at a solution

    This solution is given as well.


    I don't understand how he construct it. I know NAND is fromed by two PMOS in parallel at top and two NMOS in series at bottom. NOR is formed by two PMOS in series at top and two NMOS in parallel at bottom.

    Like, are there any rule that says, if I see (A+B), the CMOS should be in parallel or series...?

    Thank you
