1. A method for delivering an electrical stimulation pulse to tissue, said method comprising:

  • directing an acoustic transmission having an envelope and is powered by circuitry including an energy storage capacitor;

    implanting a receiver-stimulator having circuitry including an envelope detector to produce an electrical stimulation pulse having a voltage proportional to the amplitude of the envelope of the acoustic transmission; and

    delivering the electrical stimulation pulse to tissue using electrodes having a tissue-electrode impedance;

    wherein the capacitance of the energy storage capacitor is selected to produce an acoustic transmission with an envelope of decreasing amplitude.
