Challenge Problems

Push your limits with challenges.

Question 1

Suppose you have a n-p-n transistor with a base-emitter voltage of 0.7V and a collector-emitter voltage of 5V. Calculate the possible changes in collector current if the base width decreases.

💡 Hint: Consider how the alterations in the base width affects carrier dynamics.

Question 2

Design a circuit using an n-p-n transistor to amplify a weak signal. Assume relevant parameters for your design and explain calculations.

💡 Hint: Start with general transistor equations and adjust for the parameters you assume.
