    摘要： An apparatus comprises a therapy circuit that provides a neural stimulation current, an impedance measurement circuit that measures a value of impedance at the output of the therapy circuit, a supply voltage generating circuit that provides an adjustable supply voltage value to the therapy circuit including a first supply voltage value when in a first mode, and a control circuit communicatively coupled to the therapy circuit, the impedance measuring circuit, and the supply voltage generating circuit. The control circuit, upon receiving an indication to exit the first mode, initiates an impedance measurement by the impedance measurement circuit, determines the second supply voltage value using the impedance measurement, and initiates a change from the first supply voltage value to the second supply voltage value. The second supply voltage value is sufficient to operate the therapy circuit and to provide a specified load current value to the measured impedance.
