Apparatus and method assure the electrical characteristics of a stimulation
waveform to an electrode of an Implantable Neuro Stimulator. The embodiment comprises
a regulator, a measurement module, a generator, and a processor. The generator
provides an input signal to the regulator. The regulator consequently regulates
the input signal in order to form a pulse that is applied to the electrode. The
processor instructs the measurement module to perform an electrical measurement
that is indicative of an amplitude of the pulse. If the electrical measurement
is sufficiently different from a desired value, the processor instructs the generator
to be reconfigured in order that the amplitude of the pulse is within an acceptable
value. A redundant capacitor pair may be inserted in a capacitor arrangement in
order to compensate for a reduced battery voltage, or a detected faulty component
such as a capacitor or a regulator may be replaced with a redundant component.
