Q:

DMOS construction

I am learning for my exam , and i am not sure if this DMOS construction si correct. Did i make any mistake or is it as it should be?

A:

your circuit is a correct translation of the expression. here is an different circuit that gives the same result but uses only one type of gate.
Sometimes it is desirable to use several of the same type of gate for example if using 4000 series CMOS parts which typically have 4 gates of the same type
