A 25 Mbps, 12.4 pJ/bit Backscatter Data Uplink for the NeuroDisc BCI


Multi-day neural plasticity experiments in non-human primate (NHP) models require wireless neural recording with a high rate uplink and minimal power consumption. We introduce a 25 Mbps differential quadrature phase-shift keying (DQPSK) backscatter wireless uplink for the NeuroDisc brain-computer interface (BCI), operating in the 902-928 MHz industrial, scientific, and medical (ISM)-band. The backscatter uplink consumes 310 μW, yielding a communication energy efficiency of 12.4 pJ/bit.
