6.3.3. CMOS NOR Gate

Try these first

1. 1.

   What is the purpose of a CMOS NOR gate?

   Hint

   Think about what 'NOR' means.

2. 2.

   How many PMOS transistors are used in a CMOS NOR gate?

   Hint

   Recall the configuration of the gate.

3. 3.

   What is the output of a CMOS NOR gate when both inputs are high?

   • 1
   • 0
   • Undefined

   Hint

   Remember how NOR relates to OR logic.

4. 4.

   True or False: The CMOS NOR gate has NMOS transistors in series.

   • True
   • False

   Hint

   Visualize the configuration again.

5. 5.

   Design a logic circuit that can represent a combination of CMOS NOR gates to create a full adder circuit.

   Hint

   Consider the basic functions of addition and how they can combine.

6. 6.

   Theoretical analysis: If the output of a CMOS NOR gate is low, what can you infer about its inputs?

   Hint

   Refer back to the truth table to validate your inference.
