Abstract
An implantable medical device includes a transcutaneous capacitive data link circuit. The link circuit include: a first pair of capacitors each having an external electrode configured to be externally positioned on a recipient and an internal electrode configured to be internally positioned in the recipient; a first voltage driver having positive and negative terminals each connected to one of the external electrodes, and configured to generate a first voltage drive signal responsive to a first input control signal; and a first differential amplifier circuit connected to the internal electrodes, configured to generate a first output data signal representative of the first input control signal.
