This set of MCQs helps students to learn about MOS and BiCMOS circuit design processes, describing design processes that are always associated with certain concepts like stick diagrams and symbolic diagrams .But the key element is a set of design rules which forms the communication link between the designer (specifying requirements) and the fabricator (who materializes them). Design rules are used to produce workable mask layouts from which the various layers in silicon will be formed or patterned.
