摘要
A pipeline analog to digital converter comprising: a first analog to digital converter for determining a first part of an analog to digital conversion result, and for forming a residue signal; an amplifier for amplifying the residue signal, the amplifier including at least one offset sampling capacitor for sampling an offset of the amplifier, wherein at least one resistance is associated with the at least one capacitor so as to form a filter, and the at least one resistor is variable such that an amplifier bandwidth can be switched between a first bandwidth and a second bandwidth less than the first bandwidth during sampling of the offset.
