Abstract: A neurostimulation system (NS) includes an array of electrodes positioned within a patient with an active cathode electrode located proximate to target neural tissue. A control circuit is controls delivery of therapy during a therapy delivery interval, with the therapy being delivered between an anode electrode and the active electrode. A current regulator circuit (CRC) is connected to the cathode electrode and controls current flow through the cathode electrodes. The control circuit manages the CRC to control a discharge current flow over the discharge operation to discharge developed residual voltage between the anode electrode and the active electrode in a manner that follows an actively emulated passive discharge (AEPD) profile. During the discharge operation, the CRC is connected to the inactive electrode, and receives, as a first input, an EMI feedback signal. The CRC regulates the discharge current flow through the active electrode based on the EMI feedback signal, to maintain the AEPD profile over the discharge operation during an EMI event.
