METHOD AND APPARATUS FOR CALIBRATING DIGITAL BACKGROUND THROUGH CAPACITOR DIVISION AND SWAPPING FOR REDUCING CAPACITOR MISMATCH EFFECT OF ANALOG-TO-DIGITAL CONVERTER
摘要:
A high-quality Analog to Digital Converter (ADC) is used to calibrate a difference attributable to a capacitor mismatch in a Digital to Analog Converter (DAC). The present invention is advantageous in that it can fabricate a low-power high-resolution ADC by calibrating an error attributable to a capacitor mismatch through a digital background calibration apparatus and method using a Successive Approximation Register (SAR).
