InGaAs/InP DHBT technology and design methodology for over 40 Gb/s optical communication circuits

High-performance technologies and adequate design methodologies are required to address the needs of very high-speed ICs (VHSICs) for over 40 Gb/s optical communications. We describe improvements we have introduced in our InP DHBT technology, and how our design methodology has evolved, we show how it results in improved circuit designs, and present some recent results, with some considerations on measurement limitations.
