An amplifier operating over the frequency range from 8 MHz to 20 MHz has a 10 kΩ input resistor. What is the r.m.s noise voltage at the input to this amplifier if the ambient temperature is \({27}^0C\)?


Given that,

\(k=Boltzmann^\prime s constant=1.38\times{10}^{-23}\frac{Joules}{Kelvin}\)

\(T=Temperatureoftheconductor\in Kelvin=\left(27+273\right)=300K\)



The r.m.s input noise power of the amplifier is
