Abstract: InP HBT ICs capable of 120-Gb/s multiplexing and 110-Gb/s demultiplexing operation have been developed. They feature a direct-drive series-gating configuration selector, an asymmetrical latch flip-flop, and broadband impedance matching with inverted microstrip lines. Their input sensitivity is less than 100 mV PP , and the output swing is more than 400 mV PP . To the best of our knowledge, this result is the highest data rate operation reported for electronic ICs. Moreover, error-free multiplexing and demultiplexing operation at 100 Gb/s was demonstrated.

TL;DR: An error-free multiplexing and demultiplexing operation at 100 Gb/s was demonstrated, and this result is the highest data rate operation reported for electronic ICs.

TL;DR: The genetic compositions of consecutive Japanese feeding aggregations of green turtles along the Kuroshio Current were examined by mixed-stock analyses of mitochondrial DNA control-region sequences and the significant correlation between genetic differentiation and geographical distance matrices indicated that most hatchlings from these regions transported by the KuroShio Current settle in upstream feeding grounds along the Japanese archipelago.

TL;DR: In this paper, a new approach to modeling the current vs voltage characteristics of heterojunction bipolar transistors (HBTs) is introduced, using McKelvey's flux method to treat carrier transport.

TL;DR: In this paper, the first measurement of low-frequency noise performance for self-aligned InAlAs/InGaAs HBTs was reported, and the 1/f noise obtained was around 20 dB lower than that for AlGaAs/GaAsHBTs at a fixed frequency, which is considered to be caused by the low surface recombination velocity of InGaAs.
