Composition

The capital assumption abaft CMOS circuits that allows them to apparatus argumentation gates is the use of p-type and n-type metal–oxide–semiconductor field-effect transistors to actualize paths to the achievement from either the voltage antecedent or ground. If a aisle to achievement is created from the voltage source, the ambit is said to be pulled up. The added ambit accompaniment occurs if a aisle to achievement is created from arena and the achievement pulled down to the arena potential.
