A Low-Power Hardware Stack for Continuous Data Streaming from Telemetry Implants

This paper describes the hardware implementation of a custom communication protocol tailored for low-power telemetry data streaming over an inductive link. The application-specific features of typical RFID implementations such as random number generation and variable data rate support are omitted from the proposed implementation, focusing only on the continuous data transfer. The post-synthesis results of proposed communication scheme implemented on 28nm CMOS FDSOI process show power consumption of $3.11 \mu W$ while running from a 845.7 kHz clock and occupying 0.0048 mm2 of die area. The current implementation provides an uplink rate of 8 kbit/s, sufficient for streaming of 1-channel 1 kHz 12-bit sample recording.
