Operational amplifiers (op-amps) use negative feedback in various electronic circuits to stabilize and control the gain. Negative feedback is employed to reduce distortion, increase bandwidth, and maintain precision in the output signal. It is a common technique used in amplifier, filter, and oscillator circuits to improve performance and stability.

What kind of feedback mechanism is it when it causes the initial stimulus to decline?
negative feedback
What is the difference between feedback negative feedback a negative feedback response a negative feedback mechanism and a negative feed back loop?
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
Is reflex a form of a negative feedback response?
Reflex is not necessarily a form of negative feedback response. Reflexes are quick, involuntary responses to stimuli, while negative feedback is a regulatory mechanism that helps maintain homeostasis by reducing the effects of any deviation from an ideal set point. Reflexes can be part of negative feedback loops, but not all reflexes are negative feedback responses.
Is a control mechanism that intensifies an earlier reaction A sensory receptor An effector Negative feedback Positive feedback?
sensory receptor
When the body reacts to stop or work in the opposite direction of a stimulus is it known as negative feedback or positive feedback?
When the body reacts to stop or work in the opposite direction of a stimulus, it is known as negative feedback. Negative feedback mechanisms help maintain homeostasis by reducing the effects of a stimulus to keep things within a normal range.
Which is best positive feedback or negative feedback?
Obviously,it depends on the situation. consider a transistor amplifier.To minimize the change in collector current with respect to temperature,collector to base bias is used . This circuit uses a NEGATIVE FEEDBACK in order to compensate the rise in output current with temperature. But in order to achieve maximum gain, the same circuit can use POSITIVE FEEDBACK by connecting the amplified output to the input .
Why negative feedback amplifier is preferred to positive feedback amplifier?
The negative feedback tends to stabilize the circuit; positive feedback would make it more unstable. For example, the "beta" of a transistor OF THE SAME SERIES - this is basically the amplification factor - may vary between 100 and 1000. With negative feedback, the circuit is hardly affected by these changes in beta - at the cost of a reduced amplification.
What negative feedback in a circuit?
A part of output which is provided again ti theinput but with some phase difference is called negative feedback. i hope u get it..
Is urinating a negative feedback?
Urinating is not an example of negative feedback. Negative feedback is a process that uses the result of a process to regulate the process itself, maintaining homeostasis. Urinating is a normal physiological process to eliminate waste and regulate fluid balance in the body.
What is feedback circuit?
A circuit in which output feeding back to input to increase or decrease the gain is called feedback circuit. Basically part of output feeding to input in such way that it increase the value of input is positive feedback and it also increase gain of circuit and similarly to it when part of output feeding to input in such way that it decrease the value of input is called negative feedback it also decrease the gain of circuit.
What is the feedback circuit?
A circuit in which output feeding back to input to increase or decrease the gain is called feedback circuit. Basically part of output feeding to input in such way that it increase the value of input is positive feedback and it also increase gain of circuit and similarly to it when part of output feeding to input in such way that it decrease the value of input is called negative feedback it also decrease the gain of circuit.
How does negative feedback work?
To remove the distortion ... ANSWER: It does not reduce distortion but rather make the circuit stable. There can be distortion even with negative feedback by bad design in other word feedback does not reduce distortion.
What is an example of a negative feedback in human body?

Is an amplifier a negative feedback?
Yes, Amplifire have negative feedback.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
What is negative feedback of a closed loop system?
Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
What kind of feedback is used in emitter follower?
emitter follower is a type of negative feedback ,
