Electronic Devices & Circuits Current Mirrors

In an ideal BJT current mirror using matched transistors, the reference current is 2 mA. Neglecting base currents and mismatch, the mirrored output current is approximately?

A0.2 mA
B1 mA
C2 mA
D20 mA

Show AnswerHide AnswerReport an error

Correct Answer: C. 2 mA

Explanation: For matched transistors with equal base-emitter voltage, the ideal mirror reproduces the reference current, so the output is approximately 2 mA.

Reference: Standard analog electronics: ideal BJT current mirror
