Abstract
The present disclosure provides systems and methods for generating waveforms for an implantable pulse generator of a neurostimulation system. A waveform generation system includes a computing device, at least one buffer memory, and at least one programmable current regulator. The at least one buffer memory is coupled between the computing device and the at least one programmable current regulator. The computing device is configured to load a string of output current values into the at least one buffer memory, and the at least one buffer memory is configured to sequentially feed each output current value to the at least one programmable current regulator. Further, the at least one programmable current regulator is configured to control current supplied to a plurality of electrodes based on the received output current values.
