A/D CONVERTER, IMAGE SENSOR, AND DIGITAL CAMERA |
| 摘要 |
An A/D converter includes: an A/D converter circuit that causes a dissipation current (Idis) having dependence on an input voltage (Vin); and a counteracting current generation circuit controlled based on an output digital value (Dout) provided from the A/D converter circuit to generate a counteracting current (Icnt) that is a dissipation current for reducing the dependence of the dissipation current (Idis) on the input voltage. |

1. An analog-to-digital (A/D) converter comprising:
an A/D converter circuit that causes a first current which is a dissipation current having dependence on an input voltage; and a counteracting current generation circuit that generates a second current which is a dissipation current for reducing the dependence of the first current on the input voltage, the counteracting current generation circuit being controlled based on an output digital value outputted from the A/D converter circuit according to the input voltage. |
