TIME-INTERLEAVED ANALOG-TO-DIGITAL CONVERTER

摘要

PURPOSE: A time-interleaved analog-to-digital converter is provided to have a small number of resistors, thereby effectively reducing the size of a circuit. CONSTITUTION: A first analog-digital converter(310) includes a sampling unit(301), a comparison unit(303), and a successive approximation register(305). The successive approximate register performs successive approximation of the output signals of the comparison unit. The comparison unit compares the sampled signal with a first reference voltage outputted from a reference voltage generator(340). The reference voltage generator comprises a reference voltage generating unit(343) and a controller(341). The controller provides a generated reference voltage to a plurality of analog to digital converters.
