ANALOG DIGITAL CONVERTER FOR LOW-POWER MULTI-STAGE LATCH INTERPOLATION

摘要

Provided is an analog digital converter. The analog digital converter includes: a first latch terminal which includes first latches, and each of the first latches receives an analog input voltage corresponding to an analog signal and each reference voltage, amplifies a difference between two voltages according to a first clock, and outputs a first differential (+) output and a first differential (-) output; a second latch terminal which has second latches which receive the differential output of a first latch from (+) and (-) input terminals and a second latch which receives the first differential (-) output of a first latch and the first differential (+) output of an adjacent first latch which receives a low reference voltage and the reference voltage of the first latch; and a third SR latch terminal which includes SR latches and generates interpolation output by receiving the (-) output value of a second latch and the (+) output value of a lower second latch adjacent to a second latch.;COPYRIGHT KIPO 2015
