Patent ID: 7016738

Claim:
An Implantable Cochlear Stimulation (ICS) system comprising: a microphone adapted to convert an acoustic signal into an electrical signal; a signal processor adapted to process the electrical signal to generate a processed signal, wherein the signal processor includes a push-pull Radio Frequency (RF) amplifier including a first push-pull output and a second push-pull output, wherein the push-pull RF amplifier is adapted to provide a high power mode wherein the first push-pull output and the second push-pull output are enabled to produce a swing voltage of twice the voltage of an input power signal, and wherein the push-pull RF amplifier is adapted to provide a low power mode wherein only the first push-pull output is enabled to produce a swing voltage equal to the voltage of the input power signal; a primary antenna adapted to transmit the processed signal; a secondary antenna adapted to receive the processed signal; an implantable processor adapted to receive the processed signal from the secondary antenna, wherein the implantable processor is adapted to generate a stimulation signal; and an electrode array adapted to receive the stimulation signal from the implantable array and to provide stimulation to the cochlea.
