Abstract
A method for dynamically calibrating a time-interleaved digital-to-analog converter (DAC) includes receiving a digital input signal, generating, from the digital input signal, an output analog signal using DAC circuitry, generating, from the digital input signal, a model analog signal using DAC modeling circuitry, adjusting a digital model based on the model analog signal and the digital input signal, determining at least one of an offset error and a gain error based on comparing the output analog signal to the model analog signal, and generating an error correction signal based on the at least one of an offset error and a gain error.
