Abstract

A full-rate architecture 2⁷-1 PRBS generator has been designed and fabricated in the in-house 0.5µm-emitter-width InP-HBT technology. This generator has wide-operating range from 0.1 to 48Gbps with an output swing of 345mVpp. Its power consumption is lower than 900mW. The circuit achieves error-free operation up to 12.5Gbps and we obtain correct signal sequence and good eye opening up to 48Gbps. Its FOM is lower than 2.57mW·GHz^-1.
