Abstract
An artifact-corrected time-interleaved analog-to-digital converter (ADC) for communications signals offers a significant increase in the available sample rate of ADCs by correcting timing and gain mismatches between ADC channels. These mismatches are corrected in the digital data section of a two-channel TI-ADC for band-pass input signals. This is a realistic communications system scenario as modern system designs lean towards having the ADC interface with the intermediate frequency (IF) signal in the analog section of a digital receiver rather than in the DC centered, analog down converted, in-phase and quadrature pair.
