Abstract
AlGaAs/GaAs HBTs (heterojunction bipolar transistors) with improved high-speed performance obtained by a self-alignment technology and a new layer design have been used to construct ultra-high-speed MUX (multiplexer) and DMUX (demultiplexer) ICs. Quantitative error-free operation of these ICs was confirmed up to 10 Gb/s. Although only a few test patterns were available, the maximum operation speeds of the MUX and the DMUX were found to be around 15 Gb/s and 19 Gb/s, respectively. These results demonstrate the promising potential of HBTs for coming ultra-high-speed digital systems.Keywords
