6.6. Summary of Key Concepts

Try these first

1. 1.

   What does CMOS stand for?

   Hint

   Focus on the key materials used.

2. 2.

   What function does an inverter perform?

   Hint

   Think about the opposite outputs.

3. 3.

   What type of logic gate is considered a basic building block in CMOS technology?

   • NAND
   • Inverter
   • NOR

   Hint

   Think of the function that directly changes the signal's state.

4. 4.

   True or False: Noise margins are irrelevant in CMOS gate design.

   • True
   • False

   Hint

   Consider the reliability of the circuit.

5. 5.

   Design a simple CMOS logic circuit that combines at least two types of gates (e.g., NAND and NOR) to create a specific output function. Explain your reasoning and the expected output.

   Hint

   Consider what conditions must be met for the output to be zero.

6. 6.

   Evaluate how increasing capacitance within a CMOS gate affects both propagation delay and power consumption. Discuss the trade-offs.

   Hint

   Think about how charge and discharge timing changes with capacitance.
