Abstract
A body implantable stimulator having an output capacitance that is periodically charged to a predetermined energy level and discharged through an electrode coupled to body tissue. The discharge pulse width is controlled by a semiconductor switch and after a short delay the capacitor is recharged rapidly to its original charge. The recharge current is regulated by a differential circuit responsive to the voltage on a reference capacitor and the output capacitor, both capacitors being coupled to the active electrode.
