21.6.7. Numerical Example

Try these first

1. 1.

   What is the purpose of linearization in circuit analysis?

   Hint

   Think about the benefits of simplifying complex circuits.

2. 2.

   Define transconductance.

   Hint

   It’s an important term that starts with 'g'.

3. 3.

   What does transconductance describe in a MOSFET?

   • Resistance
   • Capacitance
   • The relationship between input voltage and output current

   Hint

   Focus on how input variations influence output parameters.

4. 4.

   True or False: Small signal equivalent circuits are used to analyze large fluctuations in signals.

   • True
   • False

   Hint

   Recollect the definition of small signal models.

5. 5.

   Design a small signal equivalent circuit for a given MOSFET with specific DC parameters and derive the output voltage.

   Hint

   Don't forget to check if the MOSFET is in the saturation region for accurate analysis.

6. 6.

   If the transconductance of a MOSFET doubles, what effect does this have on the output voltage given a constant input signal?

   Hint

   Consider how a stronger relay (higher gm) influences output when you push the switch (input).
