DIGITAL TO ANALOG CONVERTER WITH HIGH RESOLUTION, CAPABLE OF OUTPUTTING THE VOLTAGE WITH HIGH PRECISION BY THE ANALOG SIGNAL COMBINATION

摘要

PURPOSE: A digital to analog converter with high resolution is provided to reduce the area of a circuit by a layout and a manufacturing cost by simplifying a circuit configuration.;CONSTITUTION: A first DAC(110) receives a first digital signal and outputs a first analog signal. A second DAC(120) receives a second digital signal and outputs a second digital signal. An attenuator(140) attenuates the second analog signal. A signal synthesizer(150) synthesizes the first analog signal and the attenuated second analog signal.;COPYRIGHT KIPO 2010
