AN INTEGRATED SYSTEM AND METHOD FOR MULTICHANNEL NEURONAL RECORDING WITH SPIKE/LFP SEPARATION, INTEGRATED A/D CONVERSION AND THRESHOLD DETECTION |
摘要 |
A CMOS integrated circuit for multi-channel neuronal recording with twelve true-differential channels, band separation and digital offset calibration. The recorded signal is separated into 2 bands: a low-frequency, local field potential (LFP); and high-frequency spike data. Digitally programmable gains for the LFP and spike bands are provided. A mixed-signal front-end processor for multi-channel neuronal recording is also described. It receives twelve differential-input channels of implanted recording electrodes. A programmable cutoff HPF blocks DC and low frequency input drift at about 1 Hz. The signals are band-split at about 200 Hz to low-frequency local field potential (LFP) and high-frequency spike data (SPK), which is band limited by a programmable-cutoff LPF. The analog signals are converted into digital form, and streamed out over a serial digital bus at up to 8 Mbps. A special interface system incorporating an embedded CPU core in a programmable logic device accompanied by real-time software allows connectivity to a computer host. |
