Abstract
A functional diagram of a novel type of A/D converter, described as bit oriented, for high-speed application is discussed. Although the system can be regarded as the natural development of the well-known flash ADC, a different approach to the conversion process has led to a reduction in the number of comparators required, with no loss in flash performances. There is also no need for sample and hold (S/H) and digital circuits for the coding. A comparison with the most up-to-date high conversion techniques (subranging, folding and interpolation) points out the advantages of the techniqueFile in questo prodotto:
