    摘要： An implantable medical device includes a radio-frequency (RF) telemetry circuit and a power connection module through which the RF telemetry circuit is connected to an energy source such as a battery. The power connection module connects power from the energy source to at least one portion of the RF telemetry circuit when a user initiates an RF telemetry session. After the RF telemetry session is completed, the power connection module shuts off the at least one portion of the RF telemetry circuit. Power-on examples include a wireless telemetry activation signal received by a low power radio receiver in the implantable device, a physical motion detected by an activity sensor in the implantable device, an activation of an inductive telemetry circuit in the implantable device, a magnetic field detected by a magnetic field detector in the implantable device, and/or a telemetry activation signal detected by a sensing circuit included in the implantable device. Power-off examples include a wireless termination signal received by the implantable device, a delay timeout following the RF telemetry session, and/or a signal received by an inductive telemetry circuit in the implantable device.

    摘要： A timing circuit especially designed for use in implantable medical devices provides both a low frequency clock and a high frequency clock. The low frequency clock and high frequency clock are compared each time the oscillator producing the high frequency clock is enabled and the result of the comparison is used to retrim the high frequency oscillator to maintain a stable output frequency, even when subjected to drift. Additional circuitry is provided for signaling an oscillator fault in the event that an error signal resulting from the comparison of the low frequency clock with the high frequency clock exceeds a predetermined limit value. Digital trim values are stored for fast and controlled oscillator start-up.
