Abstract
In this paper, we propose a mixed-mode baseband chain using a high-speed analog Viterbi decoder. The circuit system architecture is presented with a link budget calculations and the baseband circuitry is introduced. Our target performance is 125 Mbit/s and 1 GbWs throughput at the distances of 10 and 1 m using a 1 GHz bandwidth dedicated to UWB systems between 3.1-4.9 GHz utilizing the analog Viterbi decoder. Proposed analog receiver architecture makes possible high-speed communication with decreased power consumption.
