Abstract: An analog to digital converter for converting an analog signal to a digital signal by sampling the analog signal to generate the digital signal, the analog to digital converter being configured to acquire a first sample comprising a first plurality of bits that is representative of the digital signal, determine one or more bit positions within the first plurality of bits that are variable, determine one or more bit positions within the first plurality of bits that are static, and acquire a second sample after having acquired the first sample, the second sample comprising a second plurality of bits that is representative of the digital signal, wherein for the acquisition of the second sample at least a portion of the one or more bit positions that are variable have their bit values generated by sampling of the analog signal, and each of the one or more bit positions that are static have their bit values set to the same bit value as the bit value of the corresponding bit position in the first sample.
