Community Answer
If Av(d) = 3500 and ACM = 0.35, then CMRR is :a)1225b)10000c)40 dBd)80...
Given:
Av(d) = 3500 (voltage gain)
ACM = 0.35 (common mode gain)
To find:
CMRR (common mode rejection ratio)
Solution:
1. Definition of CMRR:
CMRR is a measure of how well an amplifier rejects common mode signals. It is defined as the ratio of the differential mode gain to the common mode gain.
CMRR = Av(d) / ACM
2. Substituting the given values:
CMRR = 3500 / 0.35
= 10000
3. Conversion to dB:
CMRR (dB) = 20 log10 (CMRR)
4. Calculating CMRR in dB:
CMRR (dB) = 20 log10 (10000)
= 20 * 4
= 80 dB
5. Final answer:
Therefore, the CMRR is 10000 and 80 dB.
Av(d) = 3500 (voltage gain)
ACM = 0.35 (common mode gain)
To find:
CMRR (common mode rejection ratio)
Solution:
1. Definition of CMRR:
CMRR is a measure of how well an amplifier rejects common mode signals. It is defined as the ratio of the differential mode gain to the common mode gain.
CMRR = Av(d) / ACM
2. Substituting the given values:
CMRR = 3500 / 0.35
= 10000
3. Conversion to dB:
CMRR (dB) = 20 log10 (CMRR)
4. Calculating CMRR in dB:
CMRR (dB) = 20 log10 (10000)
= 20 * 4
= 80 dB
5. Final answer:
Therefore, the CMRR is 10000 and 80 dB.
