Abstract

A monolithic four-channel DEMUX for 40 Gb/s fiber optic applications was described. The circuit used AlInAs/InGaAs HBT technology. Peak fT and fmax of 140 GHz at approximately 300kA/cm2 was noticed on measurements of transistors. The maximum current in any device was half of the current at which the peak fT occured. The reliability improved because of the reduction of current as generally failure mechanisms were thermally activated. A binary tree was used by the four channel DEMUX core. A hybrid combination of analog and microwave techniques formed the circuit.
