Abstract :
Data converters are an essential component in any communication system link. Time-interleaving several data converters is an effective way to enhance the overall bandwidth of the data-converter. However, mismatches between individual channels in time-interleaved data-converters manifest as a lower available dynamic range. A novel adaptive signal-conditioning technique is proposed to correct for the channel-mismatch errors with minimal hardware requirements. Behavioral simulations corroborating the same are presented.
