1. A method for operating a pulse generator comprising a plurality of electrode nodes each configured to be coupled to one of a plurality of electrodes in contact with a patient's tissue, comprising:
actively issuing a first pulse at two or more of the electrode nodes during a first period;
actively issuing a second pulse at two or more of the electrode nodes during a second period; and
executing a recovery period between the first pulse and the second pulse, wherein no pulses are actively issued at the electrode nodes during the recovery period, wherein during the recovery period a plurality of discharge pulses are issued to passively recover charge during each of the discharge pulses,
wherein the plurality of discharge pulses are issued by repeatedly closing and opening passive charge recovery switches connected to at least some of the electrode nodes.
