Project abstract
A re-configurable or software-defined radio transceiver should be able to adapt to different radio standards, such as the cellular and the wireless LAN ones, in the frequency range 1-6 GHz. The hardware adaptation would simplify the overall system and save considerable silicon area.
Reconfigurable transmitters may be enabled by the availability of wide-bandwidth fine-resolution frequency synthesizers.
The goal of this research program consists in conceiving new architectures for direct-digital-modulation frequency synthesis. The feasibility of such techniques will be demonstrated in 90-nm CMOS technology.
The scientific literature on this subject has been evaluated. Methodologies for the analysis and the simulation of these mixed-mode systems have been developed. The project is currently in the phase of conceiving and experimenting innovative architectures.
