12.1. Analog Electronic Circuits

Try these first

1. 1.

   What is the main difference between p-MOS and n-MOS transistors?

   Hint

   Consider the type of charge carriers.

2. 2.

   What does the threshold voltage (V_T) represent?

   Hint

   Think about the voltage needed to turn on the device.

3. 3.

   What type of charge carriers do p-MOSFETs conduct?

   • Electrons
   • Holes
   • Neutrons

   Hint

   Remember the difference in charge carriers for both types.

4. 4.

   True or False: The gate of a p-MOSFET must be at a higher potential than the drain.

   • True
   • False

   Hint

   Think about the voltage conditions for operation.

5. 5.

   You have a p-MOSFET with a threshold voltage of -1V. If you apply a gate-source voltage of -2V and a drain-source voltage of -3V, calculate the current through the device.

   Hint

   Ensure you account for the negative signs correctly.

6. 6.

   Describe the effects of increasing V_DS while V_GS is held constant on a p-MOSFET's performance.

   Hint

   Consider how voltage influences channel characteristics.
