这种有源探针可用于细胞外神经生物电位的长期记录，并可作为闭环神经假体的基础。探头集成了片上电路，用于放大，多路复用和缓冲从间隔100-/spl μ m /m的10个记录电极记录的神经信号。它只需要三根引线，并从单个5v电源运行。片上自检电路，用于测试电极阻抗水平提供。片上电路采用6- 1 /spl μ m LOCOS增强耗尽NMOS技术，在1.3 mm/SUP / /的芯片面积上制造，功耗为5 mW。探针长4.7毫米，厚15 /spl μ m，刀柄从底部附近的160 /spl μ m逐渐变细，到尖端附近的不到15 /spl μ m。
This active probe can be used for the long-term recording of extracellular neural biopotentials and as a basis for closed-loop neural prostheses. The probe incorporates on-chip circuitry for amplifying, multiplexing, and buffering neural signals recorded from ten recording electrodes spaced 100-/spl mu/m apart. It requires only three leads and operates from a single 5-V supply. On-chip self-test circuitry for testing electrode impedance levels is provided. The on-chip circuitry is fabricated in a die area of 1.3 mm/SUP 2/ using 6-/spl mu/m LOCOS enhancement-depletion NMOS technology, and dissipates 5 mW of power. The probe is 4.7 mm long and 15 /spl mu/m thick, and has a shank which tapers from 160 /spl mu/m near the base to less than 15 /spl mu/m near the tip.
