7.2. Basic CMOS Digital Circuits

Try these first

1. 1.

   What does an Inverter do?

   Hint

   Think about negation.

2. 2.

   What is the output of an AND gate when both inputs are 0?

   Hint

   Consider how AND functions.

3. 3.

   What is the primary function of a CMOS Inverter?

   • Outputs same signal
   • Outputs high only
   • Outputs inverse signal

   Hint

   Think about negation.

4. 4.

   True or False: A NAND gate produces a high output when all inputs are low.

   • True
   • False

   Hint

   Recall the behavior of NAND gates.

5. 5.

   Design a new logic gate using NAND gates only and explain how it can perform the AND operation.

   Hint

   Think about how inverting after NAND can achieve AND.

6. 6.

   If you have a series circuit with two CMOS inverters, what will the output be based on the input? Clarify your reasoning.

   Hint

   Consider how cascaded gates interact.
