Two-Stage Correction for Wideband Wireless Signal Generators with Time-Interleaved Digital-to-Analog-Converters



Youngcheol Park, Kate Remley


In this paper, a two-stage correction technique for arbitrary waveform generators that utilize time-interleaved digital-to-analog converters is presented. By analyzing and correcting the common response and imbalance response of time-interleaved digital-to-analog converters, the deterministic noise level can be lowered and the overall signal quality of the source can be significantly improved. To verify this correction technique, the improvement in a 64-quadrature-amplitude-modulated waveform with a bandwidth of 1.25 GHz at 4 GHz was evaluated. The error vector magnitude of the source was improved from 7.8% to 0.7% after implementing the proposed corrections.
