Abstract :
A 40 Gbit/s, fully differential distributed SiGe HBT driver is presented. The IC is realised in a low-cost 80 GHz production process, and is intended to operate as a modulator driver in a 40 Gbit/s fibre-optic communication system. Resulting from the differential chip architecture, no off-chip low-frequency transmission line termination networks are required, which significantly alleviates the chip mounting process. Mounted in a coaxial test fixture, an eye opening of 2 1.25 Vpp at 40 Gbit/s operation is measured.
