Abstract

This article presents the optimization process for a new architecture of digital-enhanced radio frequency receiver. This receiver is based on combining charge sampling filters and hybrid filter banks techniques. We describe the structure optimization based on a compromise between performance and implementation constraints. We then show the performances evaluation in system-level and electrical level simulations.
