Design of Sigma-Delta Converter Using 65 nm CMOS Technology for Nerves Organization in Brain Machine Interface

In this paper, an overview of the present related works in the field of neuroscience is determined. The parts of the neural interface using sigma-delta converter are examined the overall ADC is driven with low voltage to improve the control utilization in the nerves organization. In this work, a basic parts of nervous system is demonstrated which is conquer to solve the problem by delivering power and transmitting data in a minimized manner. For these the above signal is first transmitted to the brain using the help of electrode into the central nervous system of the brain where the signal is diagnosed using brain computer interface by analyzing the data from analog-digital converter. Sigma-delta converter is used for visualizing low frequency signal. Major advantage of this converter is that firstly, clocking circuit need not be design and secondly, it provides good accuracy. Actually, there is no role of digital to analog converter (D/A) connected wirelessly in proposed design. A new topology based on A/D converter, which plays a wide role to minimum supply voltage, and an inactive integrator to decrease control utilization is exhibited, for empowering an in-channel advanced converter plot in a large-scale neural recording implant.
