7.2.1. CMOS Logic Gates Recap

Try these first

1. 1.

   What does an inverter do?

   Hint

   Think about flipping a switch.

2. 2.

   What is the output of a NAND gate when both inputs are LOW?

   Hint

   Remember, NAND only outputs LOW when both inputs are HIGH.

3. 3.

   What is the function of an inverter?

   • Outputs the same signal
   • Outputs the opposite
   • No function

   Hint

   Think of it as a toggle.

4. 4.

   True or False: A NAND gate will output a HIGH signal only when both inputs are LOW.

   • True
   • False

   Hint

   Consider when the outputs are low.

5. 5.

   Design a circuit using only NAND gates that replicates the functionality of an AND gate.

   Hint

   Remember the truth table for NAND.

6. 6.

   Explain the significance of noise margins in CMOS gates and how they impact reliability.

   Hint

   Think about how stable your gate output needs to be.
