In following figure, what will be R₁ and R₂ for maximum symmetrical swing if V_CSat ≈ 0. Given that R_E = 200 Ω, R_C = 400 Ω, V_CC = 20 V, β = 99

6 k

3 k, 6 k

9.9 k, 2.4 k

2.4 k, 9.9 k

Answer : Option D

Explanation :

The quiescent collector current for maximum symmetrical swing.

In standard consideration, a factor of 10 used as the margin of inequality for β independence. Then,

V_BB = V_BEQ + I_CQ . R_E

0.7 + 16.66 x 10^-3 x 200 = 4 V
