Resonant optical receiver design by series inductive peaking for sub-6 GHz RoF

Abstract

Future wireless communication links will require ever decreasing cell sizes to provide massive data capacity densities. Implementing a fully operational base station in each cell is not viable and thus centralized solutions making use of radio-over-fiber (RoF) have been proposed. Transimpedance amplifiers (TIAs) are an essential component in such RoF links. In this article, resonant TIAs making use of series inductive peaking are proposed for RoF communication links. Such a band-pass approach benefits from superior noise behavior and a relaxation of the transimpedance limit compared to the traditional broadband designs typically used in RoF.
