Question 1

What does transconductance measure?

  • The change in collector voltage with respect to base-emitter voltage.
  • The change in collector current with respect to base-emitter voltage.
  • The change in base current with respect to collector current.

💡 Hint: Think about what input and output parameters transconductance relates.

Question 2

True or False: Higher transconductance means better amplification capability.

  • True
  • False

💡 Hint: Relate it to circuit design impacts.

Challenge Problems

Push your limits with challenges.

Question 1

If you have a transistor with a transconductance of 5 mA/V and a Q-point at which the I_C is 10 mA, how much will I_C change for a 40 mV increase in V_BE?

💡 Hint: Apply the transconductance definition to calculate the rise in current.

Question 2

A circuit with a transistor has output conductance g_o equal to 2 mS. What is the output resistance, and how does this relate to transconductance in circuits?

💡 Hint: Use the resistive properties of conductance to derive output resistance.
