Claim One:
1. An apparatus for performing high-voltage high-count neural stimulation for medical implants, comprising: an implant circuit configured for implanting as a medical implant within a patient; an external circuit which is configured for being retained externally to the patient for registering conditions to be processed and communicated as registered conditions to said implant circuit; at least one inductive coupling between said implant circuit and said external circuit over which power and data are communicated from said external circuit to said implant circuit; wherein a transmitter circuit in said external circuit and a receiver circuit in said implant circuit, utilize modulation of a carrier wave to communicate data from said external circuit to said implant circuit; a plurality of stimulator pixels arranged in at least a two dimensional array in said implant circuit, with each stimulator pixel configured with demultiplexing circuitry that demultiplexes data received by the pixel so that multiple neural stimulator outputs are generated using a shared current driver by each of said stimulator pixels; level shifting circuitry within said implant circuitry, said level shifting circuitry is configured for shifting digital signals derived from a low voltage logic supply to high-voltage signals which provides a sufficiently high-voltage for neural stimulation; and wherein said implant circuit is configured to convert registered conditions into stimulation parameters based on sensitivity thresholds for an individual patient, and to generate high-voltage neural stimulation to a high count of neural stimulator outputs.
