20-Gbit/s Multiplexer and Demultiplexer ICs Using Production-Level Silicon Bipolar Transistors

摘要

20-Gbit/s multiplexer (MUX) and demul- tiplexer (DEMUX) ICs are successfully fabricated using production--level high--performance super-self aligned silicon bipolar transistors (HSSTs) with a unity current gain cutoff frequency of 50GHz and a maximum oscillation frequency of 65 GHz.
