The first fully wireless microsystem for multichannel neural recording has been developed as a part of this dissertation. The microsystem includes a telemetry chip and an active neural recording microprobe. Powered through a wireless RF link, the bio-implantable microsystem can sample and digitize neural signals and accomplish wireless bi-directional data and power transmission.

520 $a The first fully wireless microsystem for multichannel neural recording has been developed as a part of this dissertation. The microsystem includes a telemetry chip and an active neural recording microprobe. Powered through a wireless RF link, the bio-implantable microsystem can sample and digitize neural signals and accomplish wireless bi-directional data and power transmission.
520 $a The wireless microsystem receives power from an external transmitter through an inductive RF link over a distance of 1mm to 15mm. The link is formed between an external power transmission coil and an implantable receiving coil. The telemetry chip demodulates the amplitude modulated carrier and obtains microsystem set-up control signals from the external transmitter. A bit rate of 33kbps is achieved for sending command data to the implant.
520 $a Upon receiving an effective control command, the telemetry chip sends control data to an active recording microprobe for site selection. Eight sites from a total of 64 sites on the microprobe can be selected according to the command and sampled for neural recording.
520 $a An on-chip 10-bit charge redistribution ADC converts the analog neural signal to digital format. It has an Effective Number of Bit (ENOB) of 9.3 bits and power dissipation of 1.1mW. Then an on-chip On Off Keying (OOK) active transmitter, consuming 2.2mW, is used to send the results back to an external receiver with a bit rate of 2.56Mbps. The bit error rate is less than 10 -7 over a range of 10mm or shorter and the carrier frequency is adjustable from 50MHz to 150MHz.
520 $a The microsystem has been tested in-vivo to record neural action potentials from a rat's motor cortex. Eight neural channels were sampled and recorded by using an active microprobe. The minimum detectable signal (MDS) of this microsystem is 28.8 muVrms in in-vitro testing, and the MDS is 52 muVrms in in-vivo testing. The main noise sources are environmental noise and substrate coupled noise on the active microprobe. The entire microsystem, including the active microprobe and coils, weighs 1.2g and consumes 12.7mW. The telemetry chip is fabricated in 1.5 mum AMI ABN CMOS process with a die size of 4.6 x 4.7 mm2.
