Explanation
Verified
Verified
The expression for the input thermal noise
is,
The equivalent input noise generated by the amplifier is,
Here,
is the noise produced at a temperature
and
is the noise produced at a reference temperature
of 290 K.
Equate the input noise expressions.
Therefore,
Therefore, the relation between noise figure and noise temperature is,
.
