Explanation: The output current is reflection or mirror of the reference input current. Therefore, the constant current source circuit referred as Current Mirror. 11. When will be the mirror effect valid
A. β≫1
B. β=1
C. β<1
D. β≠1
Answer:A
Explanation: The output current is reflection or mirror of the reference input current. Therefore, the constant current source circuit referred as Current Mirror. 11. When will be the mirror effect valid
A. β≫1 B. β=1 C. β<1 D. β≠1
Explanation: If value of β is used in the equation, IC=β/(β+2)×Iref. It almost become unity and the output current become equal to reference current. [/expand]
