A 100-Gb/s 1:4 Demultiplexer in InP DHBT Technology

This paper presents a 1:4 demultiplexer fabricated in InP DHBT technology. The demultiplexer is verified to work up to 100 Gb/s at a supply voltage of -3.6 V consuming 2.1 W. It is a half-rate demultiplexer using multi-phase clock architecture. To verify operation up to 100 Gb/s the authors used an in-house PRBS generator chip
