Abstract
According to embodiments, amplitude for a stimulation pulse delivered to electrodes implanted within a patient is controlled by a scale circuit and a digital-to-analog converter. The scale circuit selects one of a plurality of overlapping, different sized stimulation pulse amplitude ranges while the digital-to-analog converter selects an amplitude within the selected range. Stimulation pulse amplitude adjustment resolution scales automatically with the selected range, and a lowest range including the desired amplitude is automatically selected.
