A fully-integrated 64-channel wireless neural interfacing SoC achieving 110 dB AFE PSRR and supporting 54 Mb/s symbol rate, meter-range wireless data transmission.
Abstract
This brief presents a 64-channel fully-integrated wireless neural interfacing SoC implemented in a 65 nm CMOS process. To minimize the weight and size of the head-stage connected to the small experimental animals, the system is designed to be powered by either a single-coil 13.56 MHz wireless power receiver or a small-sized button cell battery. A replica-biased 0.35 V 110 dB PSRR LNA is introduced to tolerate the power supply noise inherently in wireless power harvesting and save power consumption. The recorded neural data is transmitted wirelessly by a 2.4/3.2 GHz dual-band OOK transmitter, which supports 54 Mb/s symbol rate, 44 pJ/bit meter-range wireless data transmission. To reduce the transmission BER, forward error correction with convolutional code and cyclic redundancy code is adopted.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
