| 摘要 | This A/D convertor includes: a first D/A conversion unit configured to sample an analog input signal, and to generate a first difference signal by performing successive comparison of the analog input signal based on a reference voltage; a precharge capacitor unit configured to hold the reference voltage; a first comparing unit configured to compare the first difference signal with a reference value to generate a first digital signal; and an amplifying unit configured to calculate by using the first difference signal and the reference voltage to generate a residual signal. | ||

| 主权项 | 1. An A/D convertor, comprising: a first D/A conversion unit configured to sample an analog input signal, and to generate a first difference signal by performing successive comparison of the analog input signal based on a reference voltage; a precharge capacitor unit configured to accumulate a charge for the reference voltage; a first comparing unit configured to compare the first difference signal with a reference value to generate a first digital signal; and an amplifying unit configured to generate a residual signal by a calculation using the first difference signal and the reference voltage. | ||
