  • Integrated circuit design for wireless control of biphasic stimulation in bioelectronic implant
    Patent number: 11167134
    Abstract: A system for providing biphasic stimulation is disclosed. The system includes an electrode, an antenna coupled to a transmitter, a capacitor, a power supply, a backscatter load selectively coupled to the antenna via a switching device, a plurality of switches, and a controller configured to control the switching device to output, by the antenna, an acknowledgement signal to the transmitter responsive to receiving the power. The controller is further configured to control the plurality of switches to electrically couple a first plate of the capacitor to the electrode to provide a first nerve stimulation signal having a first polarity, and electrically couple a second plate of the capacitor to the electrode to provide a second nerve stimulation signal having a second polarity opposite the first polarity. The system further includes a housing encapsulating the antenna, the capacitor, the power supply, the backscatter load, the switches, and the controller.
