Question 1

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

A = g_m * R_C
A = -g_m * R_C
A = g_m + R_C

💡 Hint: Consider how gain is derived mathematically.

Question 2

True or False: The output swing is unaffected by the amplifier's stability.

True
False

💡 Hint: Think about the constraints on output signal variability.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a common emitter amplifier that maintains distortion levels below a certain limit, considering power dissipation and temperature effects.

💡 Hint: Pay attention to the specifications provided by the transistor manufacturer.

Challenge 2 Hard

Given that a certain common emitter amplifier has an input resistance of 1.3 kΩ and an output resistance of 3.3 kΩ, calculate the voltage gain assuming a collector current of 5 mA.

💡 Hint: Consider what output resistance you might use in addition to the collector current.
