CMOS circuit for detection of neural impulses

Diseases resulting from obesity are increasing problem in modern society. To limit this problem research on effective therapy is indispensable. Interesting method may be stimulation of the neural system, allowing to control appetite. During our work on this subject it became necessary to design VLSI chip allowing to analyze neural impulses. In this paper the designed chip is presented. It was designed and fabricated in AMS 0.35 μm technology.
