Question 1

What does the mid-band gain represent?

It represents the maximum gain of an amplifier in a single frequency.
It indicates the gain across the entire frequency spectrum.
It shows the maximum and constant gain within a specified frequency range.

💡 Hint: Think about where in the frequency spectrum you would measure consistent gain.

Question 2

True or False: Coupling capacitors in the mid-band behave as open circuits.

True
False

💡 Hint: Think about what happens to AC signals in the presence of a short circuit.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given an amplifier with a gm of 50 mS, a rπ of 1 kΩ, and a ro of 150 kΩ, calculate the mid-band gain.

💡 Hint: Don't forget to handle the parallel resistance calculation correctly.

Challenge 2 Hard

If an amplifier's mid-band gain is 100 but the upper cutoff frequency is reduced, how would this affect audio signal amplification?

💡 Hint: Consider why full frequency response is critical for sound quality.
