A versatile low power integrated circuit for the recording and analysis of in-vivo and in-vitro neural signals

This paper proposes a high resolution recording device for medical and biological research applications investigating nerve firing patterns, especially where a high degree of spatial discrimination is required. The device has been designed for low power operation with the intention of powering by RF frequency carrier wave which will is also expected to be the basis of communication between the device and the monitoring unit. A 10bit signal resolution at variable sample rates, adjustable between 10-100 kHz by internal control logic combined with 128 spatially orientated channels will allow a highly detailed capture system suitable for complex DSP evaluation.
