7. Design and Analysis of Basic CMOS Digital Circuits

Try these first

1. 1.

   Name one advantage of CMOS technology.

   Hint

   Think about the impact of power on mobile devices.

2. 2.

   What does a CMOS inverter do?

   Hint

   Consider the output when the input is high or low.

3. 3.

   What is the main function of a CMOS inverter?

   • Output the same input
   • Output the inverse of the input
   • Increase input voltage

   Hint

   Think about the 'NOT' operation.

4. 4.

   True or False: A NAND gate is a universal gate.

   • True
   • False

   Hint

   Consider the versatility of NAND gates.

5. 5.

   Design a complete truth table for an XOR gate and explain its operation.

   Hint

   Think about the exclusive nature of the XOR operation.

6. 6.

   Calculate the dynamic power consumed in a circuit with a load capacitance of 10pF, a supply voltage of 3V, a frequency of 1GHz, and an activity factor of 0.2.

   Hint

   Use the formula provided earlier and plug in the values carefully.
