Abstract
A high-speed multiplexer integrated circuit capable of handling four simultaneous data channels without external delay lines is presented. The experimental circuit features an inherently fast two-stage configuration, with operation up to 27 Gb/s demonstrated based on a baseline AlGaAs/GaAs heterojunction bipolar technology. The system clock frequency is one-half of the bit rate, with only one additional self-generated internal clock necessary. A unique circuit topology has been chosen, which acquires, delays, regenerates, and retimes the incoming data.<>Keywords
