Pipeline vs. Sigma Delta ADC for Communications Applications
The Analog-to-Digital Converter (ADC) is a key component in digital communications receive channels, and the correct choice of ADC is critical for optimizing system design. In this article, we discuss what design factors drive the selection of the ADC, howto specify the ADC and when to choose between a Pipeline ADC and a Sigma-Delta (∑Δ) ADC.
●ADC:
Two of the most popular ADC architectures today are the Pipeline ADC and the Sigma-Delta ADC. Traditionally each has had its own distinct application areas, andinterestingly, nowadays, there are some areas where both can be applied. We will look at this and determine how to make the appropriate ADC choice.
●Conclusion:
Choosing the correct ADC is a crucial step in designing the optimum receive path, and attention must be paid to accurately specify the ADC by taking the full system into consideration. The information provide in this article should prove useful in making this selection.At Dialog, we have a comprehensive offering of high performance, low power, silicon proven ADC’s for pipeline and architectures covering input bandwidths from 100kHz to 100MHz, in advanced deep sub-micron technologies and in multiple foundry processes.
