Question 1

What is the formula for calculating voltage gain in a common emitter amplifier?

A_v = g_m * R_C
A_v = -g_m * R_C / (1 + g_m * R_E)
A_v = g_m + R_E

💡 Hint: Look for a formula including both R_E and R_C.

Question 2

True or False: Increasing the emitter resistance will increase the voltage gain.

True
False

💡 Hint: Recall the effect of R_E on gain from our discussion.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a common emitter amplifier with a desired voltage gain of -10. Given the transconductance g_m is 0.01 S, determine the required values of R_C and R_E.

💡 Hint: Start with assumed R_E values and calculate R_C accordingly.

Challenge 2 Hard

Evaluate how the choice of R_E affects both gain and stability in the amplifier circuit under varying temperature conditions.

💡 Hint: Consider how gain and biasing interact and affect overall performance.
