What is Bandwidth of RF amplifier?
That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
What is the importance of the quality factor Q of a tuned amplifier?
If quality factor is greater then bandwidth will also greater
Need of multistage amplifier?
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
What is Full power bandwidth of an operational amplifier?
everyone, As far as I know the Full power bandwidth is the output bandwidth of the signal when it is made to obtain the max power from output suppose max output voltage is +/- 10 V as prescribed in the data sheet and the slew rate is 600V/u sec , then the full power bandwidth will be 600/(2*pi*10) that is 9.548 MHz
What is the configuration of cascade amplifier?
In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.
What is effect on bandwidth due to positive feedback amplifier?
bandwidth decreases
What happens when the bandwidth of the amplifier increases?
When the bandwidth of an amplifier increases, it means the amplifier can process a wider range of frequencies. This can result in better signal quality and improved overall performance of the amplifier. However, increasing bandwidth may also lead to increased noise and distortion in the output signal.
If bandwidth of amplifier reduced then thermal noise in amplifier?
thermal noise willbe reduce
What is the purpose of determining frequency response?
frequency response curve helps us to find the bandwidth of particular amplifier circuit. Bandwidth is the range of frequency at which the amplifier works better....
What is the bandwidth of an amplifier that produces a square wave with a rise time of 000002 second?
The bandwidth of an amplifier can be estimated using the rise time (tr) of the output signal with the formula: Bandwidth (BW) ≈ 0.35 / tr. For a rise time of 0.000002 seconds (2 microseconds), the bandwidth would be approximately 0.35 / 0.000002 = 175,000 Hz, or 175 kHz. This estimation assumes that the amplifier behaves in a way consistent with conventional bandwidth-rise time relationships.

What is unity gain bandwidth?
Unity gain bandwidth is the frequency at which an amplifier's gain drops to one (0 dB). It is a critical parameter in evaluating the performance of amplifiers, particularly operational amplifiers, as it indicates the range of frequencies over which the amplifier can effectively amplify signals without significant loss in gain. The unity gain bandwidth is inversely related to the gain of the amplifier; as the gain increases, the bandwidth decreases. This relationship is essential for designing circuits that require specific frequency response characteristics.
Working of Rc coupled amplifier using negative feedback?
As gain increases bandwidth decreases.
What is the importance of the quality factor Q of a tuned amplifier?
If quality factor is greater then bandwidth will also greater

How does bandwidth of a current series feedback amplifier change with frequency?
Bandwidth does not change with frequency. Bandwidth defines (part of) how the response of a circuit changes with frequency. Other things that define how the response of a circuit changes with frequency are: phase shift, roll-off rate, linearity of the passband, etc. but bandwidth ignores these.
What is the use of finding the bandwidth of an amplifier?
A: Any amplifier will have greater band with if operated open loop. It will also be very unstable so negative feedback is implemented for that reason. There is some drawback when feedback the band width of the amplifier decreases, So is important to find out if the amplifier when stable will it have the band width required
