Readout-noise

The readout-noise is the noise which is seen in the bias level. This is produced by the on-chip amplifier and other sources of noise in the data transmission before the signal is converted into a digital representation by the ADC. Typically this can be represented by one value which is an estimate of the standard deviation of the bias level values.
