摘要：
一种模数转换方法，用于将一种差值信号分量转换成数字数据，所述差值信号分量表示将要被处理的模拟信号中的参考分量和信号分量之差，在第一处理中，将相应于参考分量和信号分量之一的信号与用于转换成数字数据的参考信号进行比较。在比较的同时以递减计数模式和递增计数模式之一执行计数，并在比较结束时保持计数值。在第二处理中，将相应于参考分量和信号分量中的另一个分量的信号与参考信号进行比较。在比较的同时以递减计数模式和递增计数模式中的另一种模式执行计数，并在比较结束时保持计数值。
摘要（英）：

In an analog-to-digital conversion method for converting a difference signal component representing a difference between a reference component and a signal component in an analog signal to be processed into digital data, in a first process, a signal corresponding to one of the reference component and the signal component is compared with a reference signal for conversion into the digital data. Concurrently with the comparison, counting is performed in one of a down-count mode and an up-count mode, and a count value at a time of completion of the comparison is held. In a second process, a signal corresponding to the other one of the reference component and the signal component is compared with the reference signal. Concurrently with the comparison, counting is performed in the other one ofthe down-count mode and the up-count mode, and a count value at a time of completion of the comparison is held.
