Design of a QDI asynchronous AER serializer/deserializer link in 180nm for event-based sensors for robotic applications

On-chip AER serialization is a required step for the successful integration of event-driven neuromorphic devices on complex robotic platforms. We propose an architecture and its implementation on AMS 180nm technology, synthesised with the Quasi-Delay Insensitive design principles and with minimum timing assumptions. The serialization of 19 bits completes in 70ns with an average power consumption of 2.34mW.
