A survey of RF DAC Architectures
2010 (English)In: Proceedings of the Swedish System On Chip Conference, SSOCC 2010, 2010Conference paper (Other academic)
A brief overview of different approaches to implement highfrequency,digital-to-analog converters (DACs), sometimes also referredto as radio-frequency DACs (RF DACs) or mixer DACs is given.
Recently, there has been a fairly increased activity within this research field. RF CMOS processes have matured and enables a higher degree of integration with high-speed digital circuits at a more reasonable cost. Also, lately, some new advances have been reported which addresses the architectural-level design issues. These new advances include, for example, the implementation of high-speed, digital sigma-delta modulators to be used with RF DACs to further enable an increase of the output frequency of the DACs.
This work presents a small survey on how RF DACs operate and in some sense how they can be implemented. We outline some different architectures and discuss the pros and cons of those.
