Abstract
The present disclosure provides systems and methods for an output architecture for an implantable pulse generator of a neurostimulation system. The output architecture includes a power supply, a plurality of outputs, a global source current regulator coupled to the power supply and operable to source current from the power supply to the plurality of outputs through a plurality of source current branches, a global sink current regulator operable to sink current from the plurality of outputs to ground through a plurality of sink current branches, a current source branch selector operable to select, for each of the plurality of outputs, an amount of current sourced from the plurality of source current branches, and a current sink branch selector operable to select, for each of the plurality of outputs, an amount of current sunk to the plurality of sink current branches.
