Abstract
Apparatus is provided for stimulating a tissue having a tissue capacitance. The apparatus comprises a capacitor, and circuitry which is adapted to charge the capacitor to a potential, and discharge the capacitor for a discharge period through the tissue. The apparatus further comprises a resistive element, having a resistance which is controlled by the circuitry, which is coupled to the circuitry, and which is adapted to substantially short-circuit the tissue capacitance responsive to a control signal generated by the circuitry.
