Yes, Amplifire have negative feedback.
there are four types of feedback connetion. the one used is that which amplifies your input (Positive feedback).
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.
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Because the feedback of an amplifier tends to reduce the gain of an amplifier and also, the bandwidth of feedback increases the gain of an amplifier, so in an high gain amplifier as to be stabilized. BY ENGINEER MUHAMMED OLALEYE OLUWATOSIN TELECOMMUNICATION STUDENT, RUFUS GIWA POLYTECHNIC, OWO
Yes, Amplifire have negative feedback.
A negative feedback amplifier (or more commonly known as feedback amplifier)can be defined as an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
feedback that reduces gain to help stabilize amplifier operation. gain is easy and cheap to get, stability isn't. its a tradeoff. so amplifier is deliberately designed with much more gain than needed and negative feedback sacrifices some of that gain to stabilize it.
Reduce the distortion in output signal.
A: An amplifier operates withing its open loop response a negative feedback insure that the amplifier remains in its linear region. therefore reducing effects of saturation, storage time to name a few.
describe current-shunt negative feedback as applied to operational amplifiers, including derivations of the gain relation for each type of negative feedback.

An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.
The series input resistor and the feedback resistor.
One method is by adding negative feedback from the output to the input stages.
