For the amplifier shown determine the value of the bias current (Ib) and input offset current (Io) respectively.

(a) Ib = IB1 + IB2 Io = IB1 – IB2

(b) Ib = IB1 + IB2 Io = | IB1 – IB2 |

(c) Ib = 0.5(IB1 + IB2) Io = | IB1 – IB2 |

(d) Ib = 0.5(IB1 + IB2) Io = IB1 – IB2

the question was asked during an internship interview.

Best answer
Right answer is (c) Ib = 0.5(IB1 + IB2) Io = | IB1 – IB2 |

The best I can explain: Standard mathematical expressions are used with the given variables.
