Design of Wideband Architectures for Modern Communication Standards

Modern communication standards demand wideband solutions, with increasing channel bandwidths. At the same time, massive MIMO is quickly approaching, asking for low-cost and low-power architectures. This thesis is focused on the design of RF blocks, suitable for state-of-the-art applications. The work is divided in two parts. In the first one an innovative transmitter architecture based on a current-mode passive mixer topology with a closed-loop RF amplier is presented. The second part deals with the analysis and design of a broadband, inductorless noise-cancelling low-noise amplifier. Measurement (TX) and simulation (TX and LNTA) results are reported, to validate the proposed designs.
