TY - JOUR AB - This paper reports on a pulsed coding technique based on optical Ultra-wideband (UWB)modulation for wireless implantable biotelemetry systems allowing for high data rate link whilstenabling significant power reduction compared to the state-of-the-art. This optical data codingapproach is suitable for emerging biomedical applications like transcutaneous neural wirelesscommunication systems. The overall architecture implementing this optical modulation techniqueemploys sub-nanosecond pulsed laser as the data transmitter and small sensitive area photodiode asthe data receiver. Moreover, it includes coding and decoding digital systems, biasing and drivinganalogue circuits for laser pulse generation and photodiode signal conditioning. The complete systemhas been implemented on Field-Programmable Gate Array (FPGA) and prototype Printed CircuitBoard (PCB) with discrete off-the-shelf components. By inserting a diffuser between the transmitterand the receiver to emulate skin/tissue, the system is capable to achieve a 128 Mbps data rate with abit error rate less than 10 9 and an estimated total power consumption of about 5 mW correspondingto a power efficiency of 35.9 pJ/bit. These results could allow, for example, the transmission of an800-channel neural recording interface sampled at 16 kHz with 10-bit resolution.
