專利摘要 |
A current-mode DAC includes at least one to-be-corrected one current source, a referential current source, a current comparator for comparing the current of the to-be-corrected current source and the current of the referential current source, a correction controller, a successive approximation register controller controlled by the correction controller and referring to the result of the comparison for carrying out successive approximation, and at least one correction DAC electrically connected with the successive approximation register controller and the to-be-corrected current source for referring to the result acquired from the successive approximation register controller and then providing a bias for the to-be-corrected current source for carrying out current correction. Accordingly, the corrected current can have the excellent accuracy. |
