Types of Negative feedback amplifier?
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback
What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Is an amplifier a negative feedback?
Yes, Amplifire have negative feedback.
Why neutralisation is used in tuned amplifier?
neutralization is one of the methods to make the amplifier unilateral i.e. to remove internal feedback of the amplifier. It is done to obtain the maximum gain from an amplifier.
What is current feedback shunt?
The effect of current shunt feedback in an amplifier is to The effect of current shunt feedback in an amplifier is to
Types of Negative feedback amplifier?
voltage amplifier feedback current amplifier feedback transconductance feedback transresistance feedback
What is current series feedback amplifier and its uses?
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
In a feedback amplifier positive feedback produces an output that is?
A: POSITIVE feedback will force the amplifier to sit at its rail saturated
What is feedback amplifer?
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.
In what situation voltage feedback amplifier is used?
in automatic volume contrrol
What is the application of feedback amplifier?
A: feedback is not an application but rather is a must to keep a system or amplifier stable in the linear regions
Is an amplifier a negative feedback?
Yes, Amplifire have negative feedback.
What is negative feedback in an amplifier?
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.
What is the effect of negative feedback in a noninverting amplifier?
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
Input impedance of current shunt feedback amplifier?
The input impedance of a current shunt feedback amplifier is the open loop impedance of the amplifier divided by 1+(A*beta)
Why positive feedback is not used in amplifier?
positive feedback makes regeneration of the input signal,which creates more noise. ANSWER: To feedback positive voltage will do nothing for noise or any other reason but force the amplifier to saturate to the hi rial or the low rail of the power supply
What are the application of voltage shunt amplifier?
Applications of Voltage shunt feedback amplifier?
