Question

I’ll cash app 20 and 50 points text me after you answer.

Answer 1

Answer:

Negative Feedback Control of the Amplifier is achieved by applying a small part of the output voltage signal at Vout back to inverting (-) input terminal via the feedback resistor, RF

Answer 2

What is a negative feedback control?

A negative feedback control is part of the amplifier. This can be gained by taking a small part of voltage and putting it back to upend input terminal. This can be located in the feedback resistor.

Why is it used?

The feedback part reduces the gain in the system. The degree of reduction is similar to the open loop the system contains. Negative feedback reduces things like...

• Sensitivity
• Distortion
• Noise

...to improve the overall system bandwidth and impedance from both the input and output.

Best of Luck!
