Question 1.
What is the definition of transconductance?
Show hintHide hint
Think about the formula ΔI_C/ΔV_BE.
Question 2.
What does the term Q-point refer to?
Show hintHide hint
Connect it to the concept of biasing in circuits.
3Question 3.
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.
Show hintHide hint
Think about what input and output parameters transconductance relates.
4Question 4.
True or False: Higher transconductance means better amplification capability.
- True
- False
Show hintHide hint
Relate it to circuit design impacts.
Question 5.
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?
Show hintHide hint
Apply the transconductance definition to calculate the rise in current.
Question 6.
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?
Show hintHide hint
Use the resistive properties of conductance to derive output resistance.
