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 mVpp, 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.
