Paper Abstract

The objective of this paper is to find a method to design an active multichannel silicon microelectrode which is used to measure the neural signal. A circuit model when measuring the neural signal using the silicon microelectrode is proposed based on the structure and fabrication process of the microelectrode. The method of determining the dimensional parameters of the probe shank is discussed in the following three aspects: the structure of pallium and endocranium, efficient, coupled interconnects noise and strength characteristic of neural probe. The design criterion is to minimize the size of the neural probe and increase its stiffness to pierce the endocranium. The on-chip unity-gain bandpass amplifier has an overall gain of 40 over a bandwidth from 60Hz to 10 kHz; an input loadits resistance is designed to be above 30MΩ to guarantee a cutoff frequency below 100 Hz.
