The accelerating pace of research in neurosciences and rehabilitation engineering has created a considerable demand for implantable microsystems capable of interfacing with large groups of neurons. Such microsystems must provide multiple recording channels incorporating low-noise amplifiers, filters, data converters, neural signal processing circuitry, power management units and low-power transmitters to extract and wirelessly transfer the relevant neural data outside the body for computing and storage. This paper is reviewing several electronic recording strategies to address the challenge of operating large numbers of channels to gather the neural information from several neurons within very low-power constraints.
神经科学和康复工程研究步伐的加快，对能够与大量神经元连接的可植入微系统产生了相当大的需求。此类微系统必须提供多个记录通道，包括低噪声放大器、滤波器、数据转换器、神经信号处理电路、电源管理单元和低功率发射器，以提取相关神经数据并将其无线传输到体外进行计算和存储。本文综述了几种电子记录策略，以应对在极低功耗限制下操作大量通道以收集多个神经元神经信息的挑战。
