ABSTRACT:
An apparatus for error compensation of a self calibrating current source adapted for compensating errors of at least one self calibrating current source. The compensation apparatus includes an imitative self calibrating current source, a current source reference apparatus and an error compensation apparatus. The imitative self calibrating current source is used to simulate the structure of the self calibrating current source to generate an error bias signal as the error of the self calibrating current source. The current source reference apparatus is used to generate an ideal bias signal. The error compensation apparatus generates a compensation bias signal to compensate errors of the self calibrating current source according to the difference of the error bias signal and the ideal bias signal.
