| Abstract(in English) | This paper proposes a high-accuracy and low-power cyclic ADC using digital calibration technique. By using a cascaded cyclic ADC, we can reduce an operation speed of unit circuit and power consumption. To acieve high accuracy, new digital calibration algorithm to compensate capacitance mismatch of a switched capacitor gain stage was proposed. Utilizing the propsed ADC architecture, a 2-stage cyclic ADC with 16 bit resolution was designed using a 0.18μm CMOS technology. The ADC opeartes at 500kS/s sampling rate with 20mW power dissipation. The efffects of digtal calibration was confirmed by simulation. A calibrated Integral Non Linearity (INL) was about ±3 LSB of 16 bit. |
