Abstract :
4:1 multiplexers (Muxs) and 1:4 demultiplexers (DeMuxs) are always the bottleneck in the GHz serializer/deserializer (SerDes) implementation. This paper discusses the design of the 60 Gb/s 4:1 Mux and 1:4 DeMux with the 0.18 mum silicon germanium (SiGe) BiCMOS technology. The Mux and DeMux are controlled by a quarter clock that significantly reduces the clock frequency and relaxes the circuit design requirement. Several design techniques, such as inductive peaking and delay matching, are used in this paper to push forward the maximum data transfer rate. The output jitter of the Mux is approximately 2.2 ps. The power consumptions of the Mux and DeMux are 140 mW and 85 mW respectively.
