Abstract
The invention is directed to tri-phasic pulse generation techniques that make use of a pre-stimulus phase, a stimulus phase, and a post-stimulus phase in a pulse generation cycle. During the pre-stimulus phase, an output capacitor is charged to a desired voltage level. During the stimulus phase, the capacitor is discharged, and during the post-stimulus phase recharging of the capacitor begins again. In accordance with the invention, charging of the output capacitor can be terminated during the post-stimulus phase after a measured voltage in the patient is greater than or equal to a threshold.
