摘要： A bioamplifier that includes a high pass filter, open-loop amplifier, and low pass filter in an area efficient design that can be used in implantable neural interfaces. The high pass filter can be implemented by using a switch-capacitance resistor coupled with parasitic capacitance of the electrode. The amplifier can be chopper stabilized and can include a high gain, current-ratio first stage followed by one or more dimension-ratio stages. The low pass filter utilizes the output impedance of the open-loop amplifier to form an embedded gm-C low pass filter.

摘要： A capacitive sensor includes an upper electrode layer having a plurality of electrodes disposed in line with each other, a lower electrode layer having a plurality of electrodes disposed in line with each other, an insulating layer disposed between the upper electrode layer and the lower electrode layer, and a layer of bumps made of insulating material formed above the area where the electrodes of the upper electrode layer and the electrodes of the lower electrode later are crossed. The sensor detects the proximity of approaching objects by the capacitance change between the electrodes disposed in the upper electrode layer, and detects the contact of any objects by the capacitance change between the electrodes of the upper electrode layer and the electrodes of the lower electrode layer.

摘要： A neural interface for measuring or stimulating brain neural activity, either as a standalone unit or as a part of a larger system of similar neural interfaces. The neural interface includes a bolt-shaped housing having a tool-engaging head and threaded shank with internal circuitry and at least one electrode. In use, the housing is threaded into a cranial bore such that the electrode contacts the outer surface of the meninges. The neural interface circuitry includes an SAR ADC that provides at least rail-to-rail operation to convert received signals from the electrode(s) into digital data that can be modulated and wirelessly transmitted by intra-skin or other suitable communication.
