ABSTRACT:
A method and system utilized with an analog to digital converter is disclosed. The method and system comprise providing a first conversion on an input signal. In the first conversion, an offset error is added to the input signal to provide a first result. The method and system further includes providing a second conversion on the input signal. In the second conversion, an offset error is subtracted from the input signal to provide a second result. The first and second results are then combined to substantially remove the offset error. A system and method in accordance with the present invention compensates for the accumulated offset error over many samples, thereby achieving much higher accuracy in the offset error compensation.
