| IP개요 | Recording neuronal activity are fundamental in the neuroscience research as well as in the neural prosthetic systems enabling the treatment of neurological diseases and the restoration of sensory and motor disabilities. For example, brain machine interface that consists of multichannel neural recording system can predict behavior of paralyzed patients in real time by measuring cortical activity, and it allows the machine to conduct actions that patients want. For these purpose, research on neural interface connecting the nervous system to external device has been developed for several decades. Especially, multi-channel neural interfacing microsystem has been developed by using semiconductor process. However, current integrated circuit system has unacceptable noise level and requires a lot of power consumption to be implanted. By now, the need for appropriate approaches to design BMI circuit system gradually increased. Ultralow power consumption is pursued so that the results of this study would be used for pre-clinical and clinical applications with wireless power transfer system. The resulting neural recording system built in a standard 0.18um CMOS technology, can measure neural signal from 0.1Hz to 7kHz with very low power consumption. Our system have supply voltage under 1.8V and a power dissipation of 1uW/ch while maintain acceptable noise level |
