designing a low‑noise, high‑resolution, and portable four channel acquisition system for recording surface electromyographic signal
in current years, the application of biopotential signals has received a lot of attention in literature. one of these signals is an electromyogram (emg) generated by active muscles. surface emg (semg) signal is recorded over the skin, as the representative of the muscle activity. since its amplitude can be as low as 50 µv, it is sensitive to undesirable noise signals such as power‑line interfer...

In current years, the application of biopotential signals has received a lot of attention in literature. One of these signals is an electromyogram (EMG) generated by active muscles. Surface EMG (sEMG) signal is recorded over the skin, as the representative of the muscle activity. Since its amplitude can be as low as 50 μV, it is sensitive to undesirable noise signals such as power-line interfer...
متن کاملA Low Power Low Noise Two Stage CMOS Operational Amplifier for Biopotential Signal Acquisition System
Monitoring of the biopotential signals in present scenario attract much attention to the researcher due to increasing demand for better quality of life and to enhance interaction between humans and machines. Biopotential signals are relatively weak amplitude and low frequency in nature. Therefore it is required to design a front circuitry that defines quality of signal for processing to the nex...
متن کاملMicrotube-based electrode arrays for low invasive extracellular recording with a high signal-to-noise ratio.
We report on the development of a microtube electrode array as a neural interface device. To combine the desired properties for the neural interface device, such as low invasiveness with a small needle and a good signal-to-noise ratio in neural recordings, we applied the structure of a glass pipette electrode to each microtube electrode. The device was fabricated as sub-5-microm-diameter out-of...

برای پردازش سیگنال آنالوگ در شبکه های عصبی ، معمولا نیاز به یک واحد حافظه آنالوگ احساس میشود که بدون احتیاج به a/d وd/a بتواند بطور قابل انعطاف و مطمئن اطلاعات آنالوگ را در خود ذخیره کند. این واحد حافظه باید دارای دقت کافی ، سرعت بالا ، توان تلفاتی کم و سایز کوچک باشد و همچنین اطلاعات را برای زمان کافی در خود نگهدارد. برای پیاده سازی سیستمی که همه این قابلیتها را در خود داشته باشد، کوشش...
