In the silicon BJT circuit shown below. Assume the emitter area of transistor Q2 is two time of area of Q1. The value of Io { Let b of the transistors are very large}
  • a)
    2 mA
  • b)
    1 mA
  • c)
    4 mA
  • d)
    0.5 mA
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
In the silicon BJT circuit shown below. Assume the emitter area of tra...
      = 2mA
            Since β is very large,
            So, Iref = Ic1
i.e. Ic1 = 2mA
            Also the emitter current area of transistor Q2 is times of Q1
            So, Ic2 = 2 Ic1
                       = 2 × 2 mA
                       = 4 mA
            So, I0 = +4 mA
