80 Gb/s 2:1 multiplexer in 0.13-mm SiGe BiCMOS technology
基于0.13微米锗硅BiCMOS工艺的80 Gb/s 2:1 复接器

This work presents an ultra-high speed 2:1 multiplexer (MUX) in a SiGe BiCMOS technology with fT= 103 GHz. To boost the operating speed, the system scheme is optimized including a 2:1 selector circuit directly driving an external 50 W load, and two wide-band data buffers and one clock buffer in the input stage. The chip exhibited an open eye at 80 Gb/s with a 160 mV single-ended voltage swing.
