Challenge Problems
Push your limits with challenges.
Question 1
You are tasked with creating a current mirror from two BJTs with Ξ²=100 and Early voltage of 70 V. Assuming you need an output current of 3 mA with a reference of 1 mA, how will you configure your circuit?
π‘ Hint: Calculate based on Ξ² and determine how much current leakage could occur.
Question 2
Develop a comparative analysis of MOSFET vs. BJT current mirrors based on stability and output performance given varying Ξ² values. Present your findings.
π‘ Hint: Use quantitative examples to support your statements.
