Abstract: A circuit for generating a sign-correlated simultaneous pulsatile stimulation. The circuit includes a plurality of circuit paths coupled in parallel between a voltage rail and ground. Each circuit path includes an electrode coupled to the voltage rail via a first current source and to the ground via a second current source, the first current source and the second current source having opposite sign. A remote ground electrode is coupled to the voltage rail via a first switch and to the ground via a second switch. The stimulation is achieved by activating all current sources of the same sign and switching the remote ground electrode to create current in the remote ground electrode equal to the sum of all single electrode currents.
