摘要： The pipeline analog-to-digital converter has a number of subsequent comparator stages (2) where the thresholds of the comparator stages are adjusted in accordance with the digital conversion results from previous stages (18, 28, 38) so as to implement a non-linear conversion scale. In particular, the pipeline analog-to-digital converter consists of a number of comparator stages (2), which operate in accordance with a common clock signal. The comparator stages are connected in series in such a way that a residue signal from a previous stage is used as input signal of a subsequent stage for comparison during the next clock period of the clock signal. At least some of said comparator stages have, according to the invention, a threshold generator (25, 35, 45) for adjusting the threshold value of the respective comparator (22, 32, 42) in accordance with comparison results of previous comparator stages (18, 28, 38).
