A Sub-µW Tuneable Switched-Capacitor Amplifier-Filter for Neural Recording Using a Class-C Inverter
A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...
متن کاملMulti-electrode arrays technology for the non-invasive recording of neural signals: a review article
The recording of electrophysiological activities of brain neurons in the last half-century has been considered as one of the effective tools for the development of neuroscience. One of the techniques for recording the activity of nerve cells is the multi-electrode arrays (MEAs). Microelectrode arrays (MEAs) are usually employed to record electrical signals from electrogenic cells like neurons o...
متن کاملChronic multi-electrode neural recording in free-roaming monkeys.
Many behaviors of interest to neurophysiologists are difficult to study under laboratory conditions because such behaviors are often inhibited when an animal is restrained and socially isolated. Even under the best conditions, such behaviors may be sparse enough as to require long duration neural recordings or simultaneous recording of multiple neurons to gather a sufficient amount of data for ...
متن کاملA 1.3μW 0.0075mm Neural Amplifier and Capacitor-Integrated Electrodes for High Density Neural Implant Recording
A key issue in the design of biomedical implants is the design of low-power area-efficient circuits that allow for highdensity neural recording. This paper presents an ultra low-power (<1.4μW ), area efficient low-noise neural amplifier that utilizes current-feedback miller-compensation technique and occupies <0.08mm silicon area. Integrating the large input capacitor within the electrodes save...
متن کاملBuilding Micro-Robots: A path to sub-mm3 autonomous systems
A process for realizing sub-cubic millimeter microrobots is detailed. To date, the process has been used to produce spherical structures ranging from 0.5 mm to 3.0 mm in diameter. A model of a 0.7 mm diameter spherical robot has been developed and an estimated power budget is provided. In addition, a model of the electrostatic actuators that will be used for the robot is covered. This model has...
