Abstract:

This paper discusses one first approach towards the design of analog filter-free All-Digital RF Transmitters suitable for multi-band scenarios. In particular, the implementation of a feedforward technique will be targeted with the overall aim of analog canceling the digitally estimated out-of-band quantization noise. Simulated results are presented and evaluated in terms of Normalized Mean Square Error (NMSE), Adjacent Channel Power Ratio (ACPR) and obtained spectra.
