Calculation of Gain and Feedback Parameters


Given Parameters


  • Amplifier A = 100

  • Feedback factor B = 0.04

  • Input voltage vi = 50



Calculation of Gain with Feedback

The gain with negative feedback is given by:

G = A / (1 + AB)

Substituting the given values, we get:

G = 100 / (1 + (100 * 0.04)) = 95.24


Calculation of Output Voltage

The output voltage is given by:

vo = G * vi

Substituting the values of G and vi, we get:

vo = 95.24 * 50 = 4762 V


Calculation of Feedback Factor

The feedback factor is given by:

B = β / (1 + Aβ)

where β is the feedback voltage and is given by:

β = vo / A

Substituting the values, we get:

β = 4762 / 100 = 47.62

Now, substituting the values of β and A, we get:

B = 47.62 / (1 + (100 * 47.62)) = 0.039 = 3.9%


Calculation of Feedback Voltage

The feedback voltage is given by:

β = vo / A

Substituting the values, we get:

β = 4762 / 100 = 47.62 V


Calculation of Sacrifice Factor

The sacrifice factor is given by:

SF = (1 + AB) / (1 + B)

Substituting the values, we get:

SF = (1 + (100 * 0.04)) / (1 + 0.04) = 2.04


Conclusion

In conclusion, the gain with feedback is 95.24, the output voltage is 4762 V, the feedback factor is 3.9%, the feedback voltage is 47.62 V and the sacrifice factor is 2.04.
