ANALOG-DIGITAL CONVERTING DEVICE AND METHOD AND IMAGE SENSOR INCLUDING THE SAME |
| 摘要 |
An analog-digital converting device includes a successive approximation register (SAR) analog-digital converting circuit suitable for resolving upper N-bits for an input signal, a single-slope (SS) analog-digital converting circuit suitable for resolving lower M-bits for the input signal after the SAR analog-digital converting circuit resolves the upper N-bits, and a combining circuit suitable for combining the upper N-bits and the lower M-bits. |

1. An analog-digital converting device, comprising:
a successive approximation register (SAR) analog-digital converting circuit suitable for resolving upper N-bits for an input signal; a single-slope (SS) analog-digital converting circuit suitable for resolving lower M-bits for the input signal; and a combining circuit suitable for combining the upper N-bits and the lower M-bits to provide an output signal having (N+M) bits, M and N being positive integers. |
