(1) The document discusses constructing a CMOS static diagram based on the Boolean equations X1 = (A+B+C)D and X2 = (AB) + (CD). (2) For X1 = (A+B+C)D, the pull-up network is (A·B·C) + D and the pull-down network is (A+B+C)D. (3) For X2 = (AB) + (CD), the pull-up network is (A+B)·(C+D) and the pull-down network is (AB) + (CD).
