摘要

介绍了一种用于单片集成微电极阵列的神经刺激电路和神经信号检测电路。设计了两个运算放大器作为电路的基本单元。一种是具有低噪声和低功耗的伸缩OPA,另一种是具有轨对轨摆动和恒定gm的OPA。电路在标准的0.5 μm CMOS工艺(CSMC, Wuxi, China)上实现,并将描述电路的测试结果。

Design of neural stimulating and neural signal detecting circuit for monolithic integrated MEA
A neural stimulating circuit and a neural signal detecting circuit designed for a monolithic integrated MEA (micro-electrode array) are described. Two OPAs (operational amplifier) used as the basic cells of the circuits were designed. One is a telescopic OPA with low noise and low power, the other one is with rail-to-rail swing and constant gm. The circuits are realized in a standard 0.5-μm CMOS process (CSMC, Wuxi, China) and the test results of the circuits will be described.
