摘要：
Current generation circuitry for an Implantable Pulse Generator (IPG) is disclosed. The IPG comprises a plurality of PDACs and NDACs for souring currents to electrode nodes. The PDACs and NDACs can be configured as pairs to each provide stimulation in independent timing channels, or the PDACs can be combined and the NDACs can be combined to provide stimulation in a single timing channel. Further, the PDAC or NDAC can provide a plurality of source branch currents each of the same amplitude to the electrodes via a switch matrix, and pulse definition circuitry can be configured to always connect each of the source branch currents to one of the first one or more electrode nodes via the switch matrix.
