摘要： Provided are a voltage regulating module (100) and an implantable nerve stimulation system. The voltage regulating module (100) includes a fine regulating charge pump (10) and a voltage-multiplying charge pump (20). The first output voltage of the fine regulating charge pump (10) is Vi = m ∗ V 0 , a second output voltage of the voltage-multiplying charge pump (20) is V 2 = n ∗ V 0 , and a total output voltage of the voltage regulating module (100) is V = Vi + V 2 . V 0 is an input voltage, a value of m ranges from 0 to 1, and n is an integer greater than or equal to 1. The system uses a combination of the fine regulating charge pump (10) and the voltage-multiplying charge pump (20) to output a large-scale finely-regulatable total output voltage V, so that the actual output voltage V is close to a required stimulation amplitude as much as possible, thereby greatly reducing power consumption.

摘要： Provided is a system (40) including multiple electrodes, a treatment delivery circuit (10), a sensing circuit (20) and a controller (30). The multiple electrodes are capable of being positioned within a brain of a patient to deliver a treatment to the patient or sense an electrical activity. The treatment delivery circuit (10) is operably coupled to the multiple electrodes to deliver the treatment to the patient. The sensing circuit (20) is operably coupled to the multiple electrodes to sense the electrical activity. The controller (30) includes a processing circuit system operably coupled to the treatment delivery circuit (10) and the sensing circuit (20). The controller (30) is configured to: control, through the treatment delivery circuit (10), one or more electrodes among the multiple electrodes to deliver the treatment to the patient; sense, through the sensing circuit (20), potentials of the multiple electrodes in a process of delivering the treatment; and calculate, based on the potentials of the multiple electrodes, a difference value between potentials of any two electrodes among the multiple electrodes to obtain a voltage between the any two electrodes. The system (40) can collect the electrical signal of the deep brain of the patient in a case where the patient receives the stimulus.
