Abstract
According to another disclosed embodiment, an energy efficient implantable neurostimulator for delivering one or more electrical pulses to a target region within a patient's body is provided. The neurostimulator includes a converter for generating the stimulation current, wherein the converter includes a voltage increasing circuit and a voltage reducing circuit. The stimulator may also include a current source that includes a pair of cascode arranged transistors that are controlled to maintain an amplitude of the stimulation current substantially constant. The neurostimulator may also include a bias voltage power supply that powers a selecting circuit for selecting one of the voltage increasing or voltage decreasing circuits.
