该论文提出了一种用于经颅无线数据传输的感应耦合收发器，实现了200Mb/s的数据速率和5e-11的误码率，旨在解决植入式神经记录仪通过头皮和颅骨向外部处理器无线传输大量数据的问题。其发射能量效率达到1.5pJ/b，为高通道数神经记录系统提供了低功耗无线通信方案。
Inphi, Santa Clara, CA 1 2 Recent advancements in medical neural science and brain research have enabled the potential of uninterrupted simultaneous recording of thousands of neurons. To minimize the risk of infection to the patients, wireless data transmission is the preferred option. Therefore, the large amount of data generated by the neural recorder must be transmitted through the scalp and skull bone to an outside data processor to translate into action or to be analyzed. A next-generation 1024channel implanted neural recorder that uses 20KS/s 8b ADC to capture action and field potential can generate up to 164Mb/s data, which imposes a stringent requirement on the communication throughput of the implanted transmitter (TX). In addition, TX power consumption must be kept as low as possible for longer battery life or safe wireless power transfer, while the power consumption of the receiver (RX) chip outside the scalp can be relaxed. Current state-of-the-art
