| 20090167576 | METHOD OF STEPWISE ELIMINATING VOLTAGE OFFSET AND VOLTAGE OFFSET ELIMINATION DEVICE IN ANALOG TO DIGITAL PIPELINE CONVERTER - Disclosed is a device of stepwise eliminating an offset voltage in an analog-to-digital pipeline converter. The device includes a sub analog-to-digital converter to convert an input signal inputted from a preceding stage into a first digital signal, a sub digital-to-analog converter to convert the first digital signal into a first analog signal, and an offset removing unit to remove a part of the offset voltage according to an offset code relative to the offset voltage based on a remaining signal to thereby generate a corrected remaining signal. | 07-02-2009 |
