通过混色技术如何克服数据转换器的非线性

As communications technologies and services rapidly expand, demands for digital receivers and transmitters have grown as well. Whether the designs are focused on wide band or narrow band solutions, the same problems remain. Where can data converters be found
that exhibit near perfect dynamic performance? Where can you find a data converter capable of digitizing a GSM band for a wide band receiver which requires better than 95 dB of spurious free dynamic range? Although not possible today, the day is just around the
corner when wideband data converters will be available that exhibit 95 dB spurious free dynamic range. However through a technique know as “Dithering,” the
dynamic range of many good data converters, such as the AD9042, can be greatly expanded to meet the rigorous demands of today’s and tomorrow’s communications
needs.
