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
What else can I help you with?
If bandwidth of amplifier reduced then thermal noise in amplifier?
thermal noise willbe reduce
How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
What is a tuned rf jfet amplifier?
It's a junction gate field effect transistor that has it's bandwidth tuned to operate (amplify) in the radio frequency range.
What are the advantages of cascaded amplifier over single stage amplifier?
Cascaded amplifiers offer several advantages over single-stage amplifiers, primarily in terms of gain and bandwidth. By combining multiple amplifier stages, cascaded configurations can achieve higher overall gain while maintaining stability and linearity. Additionally, they can be designed to optimize frequency response across a broader bandwidth, allowing for improved performance in various applications. This approach also enables better impedance matching between stages, enhancing overall signal integrity.
What is the effect of bandwidth of an amplifier with negative feed back?

Which amplifier has largest bandwidth?
Direct coupled amplifier
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 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.
Why do you use feedback?
The voltage gain,input impedance,output impedance,bandwidth etc. are the characteristics of amplifier's. these are more or less constant for a given amplifier. These parameters are required to be controlled. This can be done by using feedback that's why we use feedback.
Is their any use of low input capacitance in FET?
Yes, when designing distributed amplifier, the bandwidth (cut-off frequency) is inversely proportional to Cin(Fc=1/(pi*R*Cin)). Lower Cin means higher bandwidth.
Advantages of negative feedback amplifier?
Most practical amplifier circuits use negative feedback for the following practical benefits: Stabilization of voltage gain, decreasing output impedance, increasing input impedance, decreasing distortion, increasing bandwidth.
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
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.
