Problems solved by technology
However, the way of passive charge balance makes the system have more off-chip components, the passive charge balance time is longer, and the waveform amplitude of the passive charge balance process is uncontrollable, and the control is not flexible enough.
In addition, the current implantable neurostimulation system with active charge balance function has problems such as low energy efficiency and insufficient safety of charge balance in its power usage scheme

Description
technical field [0001] The invention belongs to the field of micro medical devices, in particular to an implanted nerve stimulation system for medical use and its working method. Background technique [0002] There are many types of implanted neurostimulation systems, such as implanted deep brain stimulators, implanted spinal cord stimulators, implanted vagus nerve stimulators, etc. Pulses are generated by the stimulation output module of the implantable nerve stimulation system, and high-frequency electrical stimulation is released through implanted electrodes to stimulate nerves in specific parts of the body, thereby achieving therapeutic effects on specific diseases. [0003] When the implantable neurostimulation system is used, its stimulating electrodes are directly implanted inside the human tissue. Therefore, this type of device is directly related to the safety of the implanter, and it is necessary to achieve strict charge balance on the human nervous tissue that it...
