An RF-powered 58Mbps-TX 2.5Mbps-RX full-duplex transceiver for neural microimplants

A wirelessly-powered, high-data-rate transceiver for neuro-modulation applications is presented. The transceiver achieves 58Mbps in TX, and 2.5Mbps in RX. It enables bidirectional full-duplex communication using an external duplexer. The TX operates at 1.74GHz and consumes 93μW, while the RX operates at 1.86GHz and consumes 7.2μW. The prototype was fabricated in 40nm LP CMOS and occupies 0.8mm2. The overall system size including the duplexer is 3.2mm2.
