Q1:

In following figure, what will be R1 and R2 for maximum symmetrical swing if VCSat ≈ 0. Given that RE = 200 Ω, RC = 400 Ω, VCC = 20 V, β = 99

A 6 k

B 3 k, 6 k

C 9.9 k, 2.4 k

D 2.4 k, 9.9 k

ANS:D - 2.4 k, 9.9 k

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, VBB = VBEQ + ICQ . RE 0.7 + 16.66 x 10-3 x 200 = 4 V
