    Abstract: A method of generating at least one recommended replacement time signal for a battery is provided. The method includes measuring a plurality of associated unloaded and loaded battery voltages. A delta voltage for each associated unloaded and loaded battery voltage is then determined. A select number of delta voltages are averaged. A minimum delta voltage is determined from a plurality of the averaged delta voltages. At least one recommended replacement time signal for the battery is generated with the use of the minimum delta voltage when at least one averaged delta voltage is detected that has at least reached a replacement threshold.

    Abstract: A device for generating a plurality of output voltages from a single input energy supply source is described. The device includes a switched capacitor voltage converter that provides each of the output voltages having different supply ratios. The supply ratio is defined as a function of the input voltage provided to the switched capacitor voltage converter by the energy supply source. The switched capacitor voltage converter includes a plurality of capacitors selectively coupled to a plurality of switches that dynamically configure the capacitors into a plurality of stacked configurations. Switching between the plurality of stacked configurations may be controlled based on predetermined criteria.

    Abstract: The present invention provides an implantable medical device having at least two electrodes coupled to the device housing. The electrodes may be configured for sensing physiological signals such as cardiac signals and alternatively for providing an electrical stimulation therapy such as a pacing or defibrillation therapy. In accordance with aspects of the disclosure, the device housing provides a hermetic enclosure that includes a first housing section that is hermetically coupled to a second housing section. At least one of the at least two electrodes is coupled to an exterior surface of the first housing section that encloses the battery components of the device. The first housing section is electrically insulated from the cathode and anode of the battery.

    Abstract: Various techniques are described for periodically performing a calibration routine to calibrate a low-power system clock within an implantable medical device (IMD) based on a high accuracy reference clock also included in the IMD. The system clock is powered continuously, and the reference clock is only powered on during the calibration routine. The techniques include determining a clock error of the system clock based on a difference between frequencies of the system clock and the reference clock over a fixed number of clock cycles, and adjusting a trim value of the system clock to compensate for the clock error. Calibrating the system clock with a delta-sigma loop, for example, reduces the clock error over time. This allows accurate adjustment of the system clock to compensate for errors due to trim resolution, circuit noise and temperature.

    Abstract: Voltage supply and method having a first reference and a second reference. The first reference has an operation mode configured to supply a first reference voltage at a first accuracy and consume an operation power and a standby mode configured to consume standby power less than the operation power. The second reference is configured to supply a second reference having a second accuracy less than the first accuracy of the first reference and which consumes a second reference power less than the operation power of the first reference, the second reference voltage being trimmable based, at least in part, on a comparison of the first reference voltage to the second reference voltage.
