Question 5.
You are tasked with creating a current mirror from two BJTs with β=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?
Show hintHide hint
Calculate based on β and determine how much current leakage could occur.
Question 6.
Develop a comparative analysis of MOSFET vs. BJT current mirrors based on stability and output performance given varying β values. Present your findings.
