Very high (over 40 Gb/s) speed circuits for optical communications design methodology and application examples

Abstract

The important increase of communication services, and particularly the Internet traffic, needs to be supported by the development of adequate communication networks. High speed electronic circuits can be successfully used in MultiGigabit-rate Time Division Multiplexing (TDM) transmission systems. In this paper we discuss main characteristics and challenges of ICs for optical communications. The design methodology, and necessary CAD tools are presented. MS-DFF design for 40 Gb/s is given as an example.
