SENSOR SYSTEM USING MULTIPLE MODES FOR ANALOG TO DIGITAL CONVERSION |
| 摘要 |
A device for converting analog to digital is disclosed. The device includes a dual mode converter and a control unit. The dual mode converter has a coarse mode and a fine mode. The dual mode converter is configured to receive an input signal and convert the input signal to a digital output having a selected resolution. The control unit is coupled to the dual mode converter and is configured to operate the converter in the coarse mode until a coarse approximation is obtained and to operate the converter in the fine mode until a fine approximation is obtained having the selected resolution. The fine mode includes multi-bit incremental tracking. |

1. A device for converting analog to digital, the device comprising:
a dual mode converter having a coarse mode and a fine mode, the dual mode converter configured to receive an input signal and convert the input signal to a digital output having a selected resolution; and a control unit coupled to the dual mode converter and configured to operate the converter in the coarse mode until a coarse approximation is obtained and to operate the converter in the fine mode until a fine approximation is obtained having the selected resolution, wherein the fine mode includes multi-bit incremental tracking, wherein the control unit is configured to vary a step size employed in the coarse mode or the fine mode of the dual mode converter in a linear or non-linear manner. |
