Me 3. I24%) Determine resistances are accurate to within ±1%. r,, R. A and CMRR in dB ifA,-- 100 V/V. Assume =100 and the collector (c) A b) R (d) CMRR (dB)- + 15 V 10 kn Q, 150 150 200 k l mA Page 4 of 6

Solution

CMRR = Ad/Ac

Vo = vd*Ad + vc* Ac

vd= v1-v2

vc = v1 + v2 /2

vo = 15 - 15(5/10)

= 7.5 V
