    • In an analog to digital converter of the type wherein an analog input voltage is compared, at a comparator with a known reference voltage selected based on a digital data produced from a control circuit, an updated digital data is generated based on a result of the comparison, and the above operation is repeated to perform digital conversion sequentially from higher bit to lower bit, there are provided two capacitors of capacitances at a predetermined ratio which is so determined as to reduce the number of serial resistors in a voltage generator circuit adapted to generate the reference voltage based on the digital data produced from the control circuit, and a voltage developing at a junction between the two capacitors is coupled to the input of the comparator, so that a change in voltage of the voltage generator circuit is reduced at a predetermined ratio in accordance with electric charge distributed on the two capacitors and is applied to the input of the comparator.
    • 在比较模拟输入电压的模数转换器中,在基于从控制电路产生的数字数据选择的已知参考电压的比较器处,基于比较结果生成更新的数字数据 ,并且重复上述操作以从较高位到低位依次执行数字转换,以预定比例提供两个电容电容器,其被确定为减少适于产生的电压发生器电路中的串联电阻器的数量 基于从控制电路产生的数字数据的参考电压和在两个电容器之间的结点处产生的电压被耦合到比较器的输入端,使得电压发生器电路的电压变化在预定的 根据分配在两个电容器上的电荷的比例,并将其应用于比较器的输入。
