But if thermal is the be-all here then we've got a decent chance to track it well with a neighbouring ADC. Maybe even more precise than Chip's solution because both ADC's can run in parallel this way.Thermal noise occurs in all transmission media and all communication equipment. It occurs due to random electron motion and is characterized by a uniform distribution of energy over the frequency spectrum with a Gaussian distribution of levels. The white noise refers to the average uniform spectral distribution of energy with respect to frequency.For small analog input signals (on the order of -35dBFS), the thermal + quantization noise power dominate the ADC noise floor, which is used to approximate the ADC's effective noise figure (NF). Once the ADC's NF is known, the cascaded noise figure equation¹ can be used to determine the overall receiver noise figure at the receiver input terminal.Noise figure is the dB form of noise factor.

Input-referred noise is not to be confused with quantization noise, which is only of interest when an ADC is processing time-varying signals. In most cases, less input noise is better; however, there are some instances where input noise can actually be helpful in achieving higher resolution. The noise spectral density of an ADC can be defined easily as the full-scale signal power of an ADC less the noise power, spread across 1 Hz bandwidth unit increments. A changing FFT sampling depth does not alter an ADC’s spectral noise density. It only spreads the noise across different unit bandwidths of frequency. thermal noise is caused by the emitter, base and collector internal resistances.
