Paper Abstract

The demand for high-speed communications is growing exponentially. Recent trends in the integration of entire systems-on-chip have spurred the development of Fibre-To-The-Home (FTTH) network for high-speed data and video services. This paper presents a predistortion circuit that integrates all of the functions necessary to implement a high linearity distribution point system for broadband optical fibre communications. The single CMOS chip includes a variable gain amplifier and a predistortion circuit. The circuits have been implemented with 0.35μm CMOS technology and simulation shows that the power consumption is 86mW with a 3.3V supply. The systems and circuits are detailed and their application to analogue optical links discussed.
