41.
Calculate the stability factor and change in IC from 25°C to 100°C for, β = 50, RB/ RE = 250, ΔIC0 = 19.9 nA for emitter bias configuration.
Answer: Option
Explanation:
SICO = (1 + β).
51.
= 42.53
ΔIC = (SICO).ΔICO
= 42.53 x 19.9 nA
= 0.85 μA.

In Boylestad 11th Edition book, the formula is
(beta (1+Rb/Re))/beta+(Rb/Re).
(beta (1+Rb/Re))/beta+(Rb/Re).

Actually, the correct formula must be rb/re instead of rb/r1.
