摘要：Sample capacitor in first array of capacitor (10A \") is weighted with binarycoding; it is connected to first input end (NB+) and omnibus circuit node is charged toconversion of the voltage (grape wine) relative to ground signalling; and according toBAR technologies its by selectively with two differential reference terminals (VREFP,VrefM) simultaneously capacitor second array (10B \") be equal to first and all secondnodes (NB-) that are connected to be to be selectively connected to ground (Gnd) andlower differential voltage terminal VREFM). Two nodes are connected to comparator (23inputs). Logic unit (17 \") controls the connection of the capacitor of two arrays, accordingto predetermined timing routine is used as comparator (23 outputs). Although theconverter has a single ended input, behavior is similar to the converter 20 withDifferential Input, therefore has good immunity to interference to noise. Moreover, itdoes not need other capacitor or especially sensitive comparator, therefore, it ischaracterized in that low-power consumption and high speed, and occupies the area ofvery little, and wherein it forms the integrated circuit of part
