Abstract
Methods and systems and method for calibrating a time-interleaved Analog to Digital Converter (TIADC) are disclosed. In an example, a method for calibrating a TIADC involves a first calibration phase that involves adjusting for at least one of offset error, gain error, and time skew of M subchannels of the TIADC, and a second calibration phase that is implemented after the first calibration phase and that involves training a neural network to approximate a non-linear function of each of the M subchannels of the TIADC using an output from a reference channel as a ground truth.
