2.3.2. CMOS Inverter I-V Characteristics

Try these first

1. 1.

   What is the function of a CMOS inverter?

   Hint

   Think about how a NOT gate operates.

2. 2.

   What does the transfer characteristic curve represent?

   Hint

   Take a look at the graph discussed in class.

3. 3.

   What does a CMOS inverter do?

   • A) Inverts the input signal
   • B) Increases the signal
   • C) Stabilizes the power supply

   Hint

   Recall the basic operation of digital logic circuits.

4. 4.

   True or False: The transfer characteristic curve indicates only high voltage outputs.

   • True
   • False

   Hint

   Think of the complete behavior of the inverter.

5. 5.

   Given an NMOS transistor with a known threshold voltage, calculate the behavior of the output in a CMOS inverter for given input voltages.

   Hint

   Remember to account for both NMOS and PMOS actions.

6. 6.

   Explain how variations in supply voltage affect the output characteristics in a CMOS inverter application.

   Hint

   Think about how voltage changes impact transistor behavior.
