21.1. Analog Electronic Circuits

Try these first

1. 1.

   What is the main purpose of linearization in circuit analysis?

   Hint

   Think about how we can make complex circuits easier to understand.

2. 2.

   Define transconductance.

   Hint

   It's an important parameter for how responsive a transistor is.

3. 3.

   What does linearization help to achieve in circuit analysis?

   • True predictive modeling
   • Increased complexity
   • Higher non-linearity

   Hint

   Remember, it’s about making things easier!

4. 4.

   Transconductance is dependent on which of the following?

   • True
   • False

   Hint

   Think about how different operating conditions can affect performance.

5. 5.

   You have a MOSFET where g_m = 3 mA/V and g_d = 0.2 mA/V. If v_gs increases by 1V and v_ds remains constant, calculate the change in the drain current.

   Hint

   Use the g_m value for immediate current response.

6. 6.

   Describe how you would adjust a circuit using MOSFETs to maintain linear operation as frequency increases beyond mid-range.

   Hint

   Which additional components will compensate for increased frequency?
