Abstract:
A dither is an uncorrelated signal, usually pseudo-random noise injected into the input of an ADC such that a given input value of the wanted signal becomes spread over a plurality of codes. This reduces the effect of DNL and also smooths the integral non-linearity (INL) response of the ADC. The advantages of introducing dither could be obtained without having to perturb the signal input to the ADC. This avoids the introduction of additional components in the ADC. The dither can be applied to the components used to form a residue of the ADC stage within a pipelined converter. For example, a dither can be applied solely to a DAC part or different dithers can be applied to a ADC and DAC parts respectively. This allows greater flexibility of linearization of the ADC response and the formation of an analog residue by the DAC.

Claim (Index 18):
The ADC of  claim 16 , further comprising:\n a succeeding stage, wherein:\n the dither generator is further operable to form a second dither which comprises a fractional value of a least significant bit of the stage ADC, and \n the second dither is used to modify with the analog input signal to be converted by the stage ADC.
