3. SECTION B : QUESTION 1
• you a CMOS IC circuit designer in a leading company ; a
customer of your company has requested you to design a
CMOS IC circuit by providing only the information of the
boolean equation; Z = ((A.C)+B) .
• Your task is to sketch a transistor level schematic diagram
and to transform it to a stick diagram using the Euler Path
method from the equation.

4. 1. Find the PUN and PDN network equation
• Z= ((A.C)+B)
PUN = Z = ((A.C)+B)
=((A'+C').B')
PDN = Z = ((A.C)+B)
= ((A.C)+B)

5. 2. Draw the transistor level schematic diagram
