6.3. CMOS NAND and NOR Gates

Try these first

1. 1.

   What is the output of a NAND gate with inputs (1, 1)?

   Hint

   Think of the condition where the NAND gate turns off.

2. 2.

   What output does a NOR gate provide when both inputs are (1, 0)?

   Hint

   Recall the condition of having at least one input high.

3. 3.

   What is the output of a NAND gate with inputs (1, 1)?

   • 1
   • 0
   • Error

   Hint

   Think of the gate's operational condition.

4. 4.

   A NOR gate outputs high when:

   • True
   • False

   Hint

   Remember its logic definition.

5. 5.

   Design a simple digital circuit that uses only NAND gates to perform the function of a NOT gate. Explain your design.

   Hint

   Consider how you can force the same input through the use of multiple gates.

6. 6.

   Construct a digital logic circuit that simulates an XOR function using only NAND gates. Provide a truth table for your circuit.

   Hint

   Think of how inputs interact to yield the desired output.
