| 发明名称 | Comparator circuit and signal comparison method | ||
| 摘要 | A comparator circuit includes a first comparator configured to store an offset during a first period, and to compare first and second input signals while compensating for the stored offset to generate a first comparison signal during a second period, a second comparator configured to compare the first and second input signals while compensating for an offset to generate a second comparison signal, and a compensation amount controller configured to control an offset compensation amount of the second comparator when the first and second comparison signals have different values. | ||

| 主权项 | 1. A comparator circuit comprising: a first comparator configured to store an offset during a first period and to compare first and second input signals while compensating for the stored offset to generate a first comparison signal during a second period; a second comparator configured to compare the first and second input signals while compensating for an offset to generate a second comparison signal; and a compensation amount controller configured to control an offset compensation amount of the second comparator when the first and second comparison signals have different values. | ||
