摘要： A bandgap voltage reference circuit implemented on an integrated circuit chip in which a proportional-to-temperature current is controlled by a current controlling resistor and converted to a voltage by a voltage controlling resistor, with either or both of the resistors being an integrated on-chip digitally trimmable resistor. The reference circuit is particularly suitable for application to circuitry used in implantable medical devices where off-chip resistors provide a channel by which noise can interfere with the operation of the circuit. The on-chip digitally trimmable resistor is implemented in accordance with the invention by a programmable switch matrix connected to a resistor network.

摘要： An implantable medical apparatus comprises a solid state electronic circuit, an ionizing radiation exposure sensor, an ionizing radiation dose rate sensor, and a controller circuit. The ionizing radiation exposure sensor is configured to detect an exposure of the solid state electronic circuit to ionizing radiation, and generate an indication of a non-single-event-upset (non-SEU) effect to the solid state electronic circuit from the exposure to ionizing radiation, wherein the sensor comprises an accumulated ionizing radiation exposure sensor. The controller circuit is configured to blank the indication from the accumulated ionizing radiation exposure sensor when the radiation dose rate sensor indicates that flux ionizing radiation exceeds a flux ionizing radiation threshold.

摘要： A cardiac rhythm management system includes a defibrillation lead impedance measurement system by which defibrillation lead impedance is measured using a test current source different from the defibrillation output supply. A resulting voltage is measured to determine the defibrillation lead impedance. Using low amplitude test currents (e.g., 10-20 milliamperes) avoids patient discomfort. Charge-balanced test currents avoids charge build-up that may interfere with sensing and avoids electrode degeneration. Different current amplitudes and resulting measured voltages provide a differential defibrillation lead impedance measurement for canceling undesired effects. Bidirectional test currents account for polarity effects on the defibrillation lead impedance measurement. A calibration/correction technique uses measurements of known resistances to correct a measurement of an unknown defibrillation lead impedance measurement.

摘要： A power management system for an implantable device is disclosed. One application is an implantable cardioverter/defibrillator. Charging circuits for implantable cardioverter/defibrillators require relatively large currents from the power supply. The present power management system provides extended device operation and reduced charge cycle time. The present system monitors both current and voltage drawn from the power supply to prevent a loss of system voltage. Elective replacement indication is performed using charging information provided by the present power management system.
