Challenge Problems
Push your limits with advanced challenges
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.
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.
