A Radiation Tolerant 4.8 Gb/s Serializer for the Giga-Bit Transceiver

This paper describes the design of a full-custom 120:1 data serializer for the GigaBit Transceiver (GBT) which has been under development for the LHC upgrade (SLHC). The circuit operates at 4.8Gb/s and is implemented in a commercial 130 nmCMOS technology. The serializer occupies an area of 0.6 mm and its power consumption is 300 mW . The paper focuses on the techniques used to achieve radiation tolerance and on the simulation method used to estimate the sensitivity to single event transients.
