Abstract
The pipeline analog-to-digital converter has a number of subsequent comparator stages () where the thresholds of the comparator stages are adjusted in accordance with the digital conversion results from previous stages () so as to implement a non-linear conversion scale. In particular, the pipeline analog-to-digital converter consists of a number of comparator stages (), 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 () for adjusting the threshold value of the respective comparator () in accordance with comparison results of previous comparator stages ().
