Abstract

High speed circuits such as multiplexer/demultiplexers, variable-gain limiting amplifiers (VGAs), and transimpedance amplifiers operating at high bit rates (>30 Gb/s) are required for the realization of high performance lightwave systems using TDM or WDM. We have demonstrated 40 Gb/s multiplexers, 30 Gb/s data and clock regeneration, DC-26 GHz VGA’s (variable gain amplifiers), and transimpedance amplifiers with 3 dB bandwidth in excess of 20 GHz for use in such systems using a manufacturable hybrid digital/microwave HBT process.
