Concept:
The noise voltage at the input of the RF amplifier is given by:
Where,
Equivalent resistance (Req) = RNoise + Rin
Boltzmann constant (k) = 1.38 × 10-23
T: Operating temperature.
B: Bandwidth of amplifier.
Calculation:
Given Equivalent resistance (Req) = 200 + 300 = 500 Ω
B = 6 MHz and T = 290 0K
Putting on the respective values, we get:
V = 6.92 μV
