Abstract:
1. A system comprising: a behind-the-ear signal processor configured to process an acoustic signal and generate one or more stimulation parameters based on the acoustic signal and configured to control an implantable cochlear stimulator, the behind-the-ear signal processor being configured to operate at a first supply voltage level; a clinician's programming interface configured to be coupled to the behind-the-ear signal processor and facilitate programming of the behind-the-ear signal processor, the clinician's programming device being configured to operate at a second supply voltage level that is different than the first supply voltage level; a voltage level translator circuit configured to facilitate communication between the behind-the-ear signal processor and the clinician's programming interface by converting digital signals that are transmitted from said clinician's programming interface to said behind-the-ear signal processor from the second supply voltage level to a voltage level substantially equal to the first supply voltage level, said conversion being based on a first input voltage signal into said translator circuit; and a circuit comprising a diode in series with a capacitor, the circuit comprising the diode in series with the capacitor configured to receive a digital signal included within the digital signals and generate said first input voltage signal by charging said capacitor to a voltage level that is substantially equal to a voltage level of said digital signal.
