Abstract
A continuous-time MASH sigma-delta analogue-to-digital converter ADC. The ADC may include first and second modulators and an output stage. The ADC may be provided with a first modulator with 1.5 bit and a second modulator with 1 bit each receiving also the feedback from the other modulator. Sampling is at higher rate at the second modulator and decimation is performed before summing its output to the output of the first modulator.
