Abstract
An apparatus comprises an electrostimulation energy storage capacitor, a circuit path communicatively coupled to the electrostimulation energy storage capacitor and configured to provide quasi-constant current neural stimulation through a load from the electrostimulation energy storage capacitor, a current measuring circuit communicatively coupled to the circuit path and configured to obtain a measure of quasi-constant current delivered to the load, and a control circuit communicatively coupled to the current measuring circuit, wherein the control circuit is configured to initiate adjustment of the voltage level of the storage capacitor for a subsequent delivery of quasi-constant current according to a comparison of the measured load current to a specified load current value.
