ANALOG TO DIGITAL CONVERTER FOR FORMING A MINIATURIZED STRUCTURE THROUGH THE SIMPLIFICATION OF AN ENTIRE STRUCTURE AND A SIGNAL PROCESSING SYSTEM

摘要

PURPOSE: An analog to digital converter and a signal processing system are provided to perform a low power operation and a high speed operation by eliminating an operational amplifier having high precision.;CONSTITUTION: An AD(Analog to Digital) conversion stage(20) of an analog to digital converter(10) comprises a signal generating unit(21), a comparison unit(22), a first output unit(23), a second output unit(24), and a conversion unit(25). The signal generating unit inputs a first analog signal and a second analog signal through a signal input line. The signal generating unit outputs the first analog signal, the second analog signal, and a third analog signal sampled to the conversion unit. The comparison unit inputs the first analog signal and the second analog signal through the signal input line. The first output unit amplifies a first residual signal provided through the conversion unit into a predetermined amplification factor. The second output unit amplifies a second residual signal provided through the conversion unit into the predetermined amplification factor.;COPYRIGHT KIPO 2012
