6.4.1. CMOS XOR Gate

Try these first

1. 1.

   What does the XOR gate output when both inputs are 0?

   Hint

   Think about how many inputs are high.

2. 2.

   List one application of XOR gates.

   Hint

   Consider logic operations in computing.

3. 3.

   What is the output of a CMOS XOR gate if both inputs are 1?

   • 1
   • 0
   • Undefined

   Hint

   Refer to the truth table.

4. 4.

   The XOR gate is used primarily in which application?

   • Data Storage
   • Arithmetic Operations
   • Signal Amplification

   Hint

   Consider tasks that require determining unique states.

5. 5.

   If two inputs are passed through a XOR gate, what is the minimum number of XOR gates needed to process three inputs together?

   Hint

   Consider how to combine two inputs at a time.

6. 6.

   Design a circuit with a CMOS XOR gate that serves as a part of a 2-bit adder. Explain the functions involved.

   Hint

   Connect the XOR gates to the input pairs to generate sums.
