摘要 为使模拟-数字信号转换芯片能直接用于各种电池电量测量的系统中而无需另加电压转换芯片,在应用于Delta-Sigma结构的ADC(模数转换器)的调制器设计中,使用0.35μm CMOS的集成电路工艺,采用二阶单环的电路结构,在5V供电的工作电压下可达到的电压测量范围为1.4V至4.2V,测量精度为12位.因而采用此Del-ta-Sigma调制器的ADC可直接用于多种电池种类的电量测量,且具有制作成本低廉的特点. In order to make the analog-digital converter can be directly used for various battery capacity measurement system without voltage conversion chip,the modulator in the Delta-Sigma ADC is designed in second-order single-loop structure with 0.35μm CMOS technology,and its measurement scope of application range 1.4 V to 4.2Vwith 12bits resolution at the 5Vpower supply.The ADC with this modulator has the advantages of wide measurement scope of range to batteries and low cost.
