Abstract
A sampling circuitry for a plurality of electrodes the circuitry comprising a plurality of charge amplifiers and a plurality of modulators, wherein each charge amplifier and each modulator, comprised in the plurality of charge amplifiers and the plurality of modulators, respectively, corresponds to an electrode of the plurality of electrodes, wherein each modulator is capable of generating a residue signal and a rough code corresponding to each sampled electrode of the plurality of electrodes, a multiplexer capable of receiving a plurality of residue signals generated by the plurality of modulators, a residue analog to digital converter capable of receiving a multiplexed residue signal from the multiplexer and outputting a digitized multiplexed residue signal, and a digital summation circuitry capable of receiving the digitized multiplexed residue signal and a plurality of rough codes, comprising each rough code corresponding to each sample electrode, and outputting a plurality of output codes.
