  • Question

  • Calculate the stability factor and change in IC from 25°C to 100°C for, ? = 50, RB/ RE = 250, ?IC0 = 19.9 nA for emitter bias configuration.


  • Options
  • A. 42.53, 0.85 ?A
  • B. 40.91, 0.58 ?A
  • C. 40.91, 0.58 ?A
  • D. 41.10, 0.39 ?A

  • Correct Answer
  • 42.53, 0.85 ?A 

    Explanation
    SICO = (1 + ?).Calculate the stability factor and change in IC from 25°C to 100°C for, ? = 50, RB/ RE = 250, ?IC0 =

    ⟹ 51.Calculate the stability factor and change in IC from 25°C to 100°C for, ? = 50, RB/ RE = 250, ?IC0 = = 42.53

    ?IC = (SICO).?ICO

    = 42.53 x 19.9 nA

    = 0.85 ?A.
