Amplifier Noise Temperature at Richard Jodi blog

Amplifier Noise Temperature. The amplifier’s gain has boosted the signal by 20 db. A body at absolute temperature t (in degrees kelvin) will emit electromagnetic. The output signal is now only 30 db above the noise. When evaluating an amplifier’s performance for a low noise application, both internal and external noise sources must be. It also boosted the input noise level by 20 db and then added its own noise. The output effective noise temperature, \(t_{\text{eff}}\), is the temperature of a resistor that would produce the same. The noise temperature of an amplifier is the temperature of a resistance that would provide the same noise power at the output of an ideal. Note that noise temperature of an amplifier is not directly related to the temperature of an amplifier. We have seen t expressed as t n, or t e (equivalent noise temperature). Amplifier noise temperatures thermal noise: The concept of noise figure allows the sensitivity of any amplifier to be compared to an ideal (lossless and noiseless) amplifier which has the same bandwidth and input.
