Challenge Problems

Push your limits with challenges.

Question 1

A BJT has a base current of 50 Β΅A and a current gain (Ξ²) of 200. Calculate the collector current and discuss its significance in a circuit application.

πŸ’‘ Hint: Make sure to remember the collector current equation!

Question 2

If a BJT's reverse saturation current is 1 nA and the applied reverse voltage is 10 V, discuss the effect this has on the junction operation and explain why this condition is essential in the design.

πŸ’‘ Hint: Consider how the reverse bias affects the depletion region size.
