Abstract
This disclosure describes techniques for generating stimulation current pulses that have differing pulse shapes in a medical device. A circuit architecture is described that is configured to charge a capacitor to an initial amount of charge, modulate the amount of charge stored in the capacitor based on a control signal, and generate a stimulation current pulse that has an amplitude based on the amount charge stored in the capacitor. The circuit architecture may be configured to generate complex pulse shapes, such as, e.g., steps, ramps, bursts, and combinations thereof.
