Abstract

This paper focuses on the investigation of integratedCMOS and Silicon/Germanium (SiGe) devices for high-speedoptical receiver circuits. In this paper, we presentseveral competitive designs of front-end transimpedanceamplifiers (TIA) for optical receiver applications using theIBM 5HP (0.5micron) SiGe technology. This technologyexhibits fT and fMAX of 47GHz and 65GHz respectively.Spectre simulations in the Cadence Affirma analog designenvironment are conducted for both the TIA's and acomplete receiver circuit consisting of a TIA, a cascadedmulti-stage differential amplifier and a multi-stageinverting amplifier at the single supply voltage of 3.3V. Wealso discuss the practicality of using SiGe basedphotodetectors for 1.3-1.5um wavelength light and the useof Neolinear's NeoCircuit/NeoCell mixed signal designtools for optimization of the analog circuits.
