Abstract
Downlink telemetry for an implantable medical device includes controlling downlink energy by generating a downlink strength signal representative of the strength of one or more downlink control bursts transmitted from an external communication device and received at the receiver of the implantable medical device. The peak amplitude of modulated downlink data bursts is controlled by adjusting the burst duration of the ramped envelope of such downlink data bursts as a function of the downlink strength signal.
