A 165-Gb/s 4:1 Multiplexer in InP DHBT Technology

This paper presents a 4:1 multiplexer fabricated in InP double heterojunction bipolar transistor (DHBT) technology. The multiplexer works up to 165 Gb/s at a supply voltage of -3.2 V consuming 1.6 W. It is a half-rate multiplexer using a multi-phase clock architecture. The main design challenge was to ensure correct timing between clock and data signals
