Abstract: As the semiconductor industry progresses towards a potential hard stop of Moore’s Law, the interface between the analog and the digital realms will continue to exist.  System designs will continue to push the digital interface closer and closer to the radio frequency (RF) front end, but it is not likely that will be a complete elimination of components to the analog-to-digital converter (ADC) or from the digital-to-analog converter (DAC) back into the RF environment.  In most cases under the advances of Moore’s Law have been realized as a parallel design implementation which may offer some incremental performance increase, but may not enable reconfigurability or adaptability depending on the application.  Furthermore, the requirement for a spatial and spectral representation of RF emissions are likely to become of even greater importance as new communication bandwidths are made available under the 5G offering.  This is likely to result in creative wave of analog, mixed-signal and digital circuits capable of simultaneous multi-functional (communications, radar, imaging, etc.) operation.  The intent of this tutorial is to identify the relevant characteristic aspects of ADCs and DACs that are likely to be integrated into a multifunctional design addressing future system design challenges.  In addition, pertinent design-to-test validation methodologies will be presented as a means to improve design robustness.
