The request for ADC specification will therefore be strict, as a result, more research will be conducted aggressively in the industrial and academic field. In order for ADC application become extensively used and correspond to the requirement of the present electronic products, four conditions need to be concerned: Speed, Resolution, Power, and Area. However, under the restriction of the factual conditions, in the process of designing, none of the ADC models was able to entirely correspond to the four conditions, thus trade-off was made for several application. This thesis refers to the 12-Bit SAR-ADC which is mainly used in electrocardiogram (ECG) measurement system. It is aimed for capturing the probability of arrhythmia through monitoring and recording ECG for a long period of time. Consequently, the power voltage was defined in 1V for low power consumption purpose. The chip was implemented by the TSMC 0.18μm 1P6M standard CMOS process technology. The sample rate is 600Hz in 150Hz signal bandwidth. Simulation results show that the SNDR and ENOB of the SAR-ADC with an input frequency of 24Hz are 67.53dB and 10.92dB. The power dissipation is 20.28μW under 1V power supply. Jen-Shiun Chiang 江正雄 2011 學位論文 ; thesis 58 zh-TW |
