Abstract :
This invited paper exposes our latest developments in the field of digital transmitters by focusing on digital and mixed-signal processing blocks, such as delta-sigma modulators, high-speed interpolation filters and digital-to-RF converters. The goal is to demonstrate that radio-frequency signal generation by mostly-digital means is competitive and not so far from being a realistic option. It will also discuss the numerous remaining bottlenecks to go through to provide reliable and attractive solutions.
