2.3. CMOS Inverter and its Behavior

Try these first

1. 1.

   What is the primary function of a CMOS inverter?

   Hint

   Think about how logic gates work.

2. 2.

   When the input to a CMOS inverter is low, what should the output be?

   Hint

   Recall how an inverter operates.

3. 3.

   What is the role of the NMOS transistor in a CMOS inverter?

   • Pulls output high
   • Pulls output low
   • Neither

   Hint

   Consider the function of NMOS in inverting.

4. 4.

   True or False: CMOS inverters have high static power consumption.

   • True
   • False

   Hint

   Think about the efficiency in current flow.

5. 5.

   Design a CMOS inverter circuit diagram, and indicate the behavior of both NMOS and PMOS transistors under varying input voltages. Include a brief explanation of how power consumption is affected.

   Hint

   Visualize how each transistor behaves with different input states.

6. 6.

   Given a CMOS inverter with specified NMOS and PMOS parameters, calculate the output voltage for various input values and describe how their I-V characteristics demonstrate inverter functionality.

   Hint

   Remember how input voltage directly influences output in the context of inverter characteristics.
