Abstract
One aspect of the present disclosure relates to a system that can provide an electric waveform for neural stimulation or nerve block. The system can include a first circuit component configured to provide a self-oscillating, voltage-boosted electric waveform. In some instances, the first circuit component can provide a “pause” waveform (e.g., with a period (T) that includes a swing time (ts) in which the waveform varies in a biphasic manner and a pause time (tp) in which the waveform has a constant amplitude). The system can also include a second circuit component configured to ensure that the oscillating signal is charge-balanced across at least one period of the self-oscillating, voltage-boosted electric waveform.
