Abstract: An implantable pacemaker detects delivery of an anti-tachyarrhythmia shock by another device. The implantable pacemaker delivers cardiac stimulation therapy within a patient. The implantable pacemaker senses, via the electrode pair, an electrical signal. The implantable pacemaker detects the anti-tachyarrhythmia shock based on the sensed electrical signal by detecting DC voltage polarization across the electrode pair within the patient. The implantable pacemaker alters the cardiac stimulation therapy based on the detected anti-tachyarrhythmia shock.

Abstract: Techniques are disclosed for generating a plurality of output voltages from a single input power source. The techniques include implementing a switched capacitor voltage converter to provide at least two 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 power source. The switched capacitor voltage converter includes a plurality of capacitors selectively coupled to a plurality of switches to define at least a first and a second mode with each of the modes having a plurality of configurations. In accordance with aspects of the disclosure, the techniques include coupling the plurality of capacitors to define the first or second mode based on predetermined criteria.

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.
