What are the factors which affects amplifier stabilization?
The main thing you need to look at to determine the stability of an amplifier is something called the K-Factor. This measures the oscillation of your amplifier in steps.
Instrumentation amplifier is used for?
used for measurement and test equipment. its used where great accuracy and stability of circuit are required.
What is the effect of feed back on gain?
A: Number one it provide stability for the amplifier or system. The greater the feedback the greater the stability but less gain. In other words gain is inversely related to feedback
Frequency compensation techniques in op amp?
This answer is not simple amplifier if the gain is unlimited will tend to oscillate at higherfrequency usually there is a pin out for some amplifiers whereby adding a snub or capacitor will limit this gain internally so it can be stabilized. There is recommended techniques by not a guaranty of stability it depends on the amplifier bandwidth factor Q and grounds and other factors.
How does using a transistor with a different beta affect the operation of the common emitter amplifier?
Gain, in the common emitter amplifier, is beta (hFe) or collector resistance divided by emitter resistance, whichever is less. Substituting a different beta (hFe) transistor will affect gain, if hFe is less, or increase stability and design margin, if hFe is greater.
What is the effect of negative feedback in a noninverting amplifier?
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.

Will gain increased bandwidth also increase to some extent after which stability decreses?
A: The question not very well formulated. But i will try to answer it. Any amplifier will have the maximum gain and the wider bandwidth when it is in a open loop situation. As feedback is added both the gain and the bandwidth will decrease but stability will increase
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.
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
Why need to stabilize amplifier?
the function of amplifier is to keep amplifying .............that is to keep multiplying the input with input to obtain larger output. hence , if this process is carried on indefinately then the system at a certain stage will not be able to retain its stability coz high of high power or output .thus it is necessary to stabalize by it by using. limter ' or threshold vaue
what are the types of biological amplifier?
1.differential amplifier 2.operational amplifier 3.instrumentation amplifier 4.chopper amplifier 5.isolation amplier
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.
