Question 1
You cascade two amplifiers, one with a gain of 20 and the other with a gain of 5. However, due to loading effect, you find an attenuation factor of 0.75. Calculate the overall gain.
π‘ Hint: Use the overall gain formula discussed in class.
Question 2
Design a buffer circuit for two amplifiers, considering you need a high input resistance and low output capacitance. Describe your design.
π‘ Hint: Think about components that have appropriate performance characteristics.
