A Flexible Low-Latency DC-to-4 Gbit/s Link Operating From -40 to +200°C in 28nm CMOS for Galvanically Isolated Applications

© 2018 IEEE. This paper presents a communication link for galvanically isolated (GI) applications. The proposed link employs a 120 GHz OOK transmitter and receiver with a PTFE fiber as directive channel to reduce transmission losses. The receiver is implemented with a replica temperature compensation loop to provide operation from -40 to +200 °C and thereby overcome the limitations of existing optical and magnetically coupled solutions. The presented work reports an isolated communication link with a data rate of 4 Gbit/s and reports the lowest latency of 1 ns with less than 4.5 % variation over the entire measured temperature range. The power consumption of the entire link is only 52.4mW and achieves 13.1 pJ/bit efficiency.
