Abstract
The disclosure provides a receiver and an automatic offset cancellation (AOC) method thereof. The receiver includes a receiving channel circuit and an AOC circuit. The receiving channel circuit generates an equalized differential signal including an equalized first-end signal and an equalized second-end signal according to an input differential signal. The AOC circuit detects a peak of the equalized first-end signal to generate a first peak detection result. The AOC circuit detects a peak of the equalized second-end signal to generate a second peak detection result. The AOC circuit compares the first peak detection result with the second peak detection result to generate a comparison result. The AOC circuit compensates a mismatch of an input differential pair in the receiving channel circuit according to the comparison result.
