7.3.4. CMOS XOR Gate Design

Try these first

1. 1.

   What does the XOR gate output when both inputs are low?

   Hint

   Think about what the exclusive OR means.

2. 2.

   True or False: The XOR gate outputs high when both inputs are high.

   Hint

   Recall the definition of XOR.

3. 3.

   What is the output of an XOR gate when both inputs are high?

   • 0
   • 1
   • Undefined

   Hint

   Think about the exclusive nature of the operation.

4. 4.

   True or False: The discrimination of outputs in XOR makes it less useful than other gates.

   • True
   • False

   Hint

   Consider where XOR is commonly applied.

5. 5.

   Design a circuit that utilizes a CMOS XOR gate and explain its real-life application.

   Hint

   Reflect on how binary numbers are added.

6. 6.

   Propose a method to improve the speed of a CMOS XOR gate in a high-speed application.

   Hint

   Focus on ways to reduce resistance and capacitance in your design.
