摘要：
In order to treat patients with advanced L-Dopamine-reactive Parkinson's disease whose symptoms cannot be effectively controlled by drugs, a stimulation circuit of a deep brain stimulator with bi-modes of voltage and current was designed and implemented. The amplitude of stimulation pulse is controlled by an adjustable stable voltage output circuit, an adjustable constant current source and an I-V Converter circuit, the frequency and width of stimulation pulse are controlled by an electronic switch, and the stimulation pulse output function for deep brain nucleus is realized by biphasic current stimulation pulses and charge-balanced voltage stimulation pulses.
