    • Miniature defibrillators and cardioverters detect abnormal heart rhythms and automatically apply electrical therapy to restore normal heart function. Critical to this function, aluminum-electrolytic capacitors store and deliver life-saving bursts of electric charge to the heart. This type of capacitor requires regular “reform” to preserve its charging efficiency over time. Because reform expends valuable battery energy, manufacturers developed wet-tantalum capacitors, which are generally understood not to require reform. Yet, the present inventors discovered through extensive study that wet-tantalum capacitors exhibit progressively worse charging efficiency over time. Accordingly, to address this problem, the inventors devised unique reform techniques for wet-tantalum capacitors. One exemplary technique entails charging wet-tantalum capacitors to a voltage equal to about 90% of their rated voltage and allowing the charge to dissipate through system leakage for a period of time, before discharging through a non-therapeutic load.
    • 微型除颤器和心脏转复器检测异常心律,并自动应用电疗法恢复正常的心脏功能。 这个功能至关重要的是,铝电解电容器可以将心脏中的电荷充满拯救生命。 这种类型的电容器需要经常的“改造”以保持其充电效率随着时间的推移。 由于改革耗费了宝贵的电池能量,所以制造商开发了湿钽电容器,通常被认为不需要改造。 然而,本发明人通过广泛的研究发现,湿钽电容器随着时间的推移呈现逐渐变差的充电效率。 因此,为了解决这个问题,本发明人为湿钽电容器设计了独特的改进技术。 一个示例性技术需要将湿钽电容器充电至等于其额定电压的约90%的电压,并且在通过非治疗负载放电之前允许电荷通过系统泄漏耗散一段时间。

    • An improved integrated self-adjustable continuous time band pass filter based upon a Gm cell with Gm compensation and bipolar transistors for use in a low power processing system for processing bursted amplitude modulated signals performing impedance-related measurements across a load. The system may be used for estimating stroke volume using the output and/or estimating hemodynamic maximum sensor rate using the output. The improved Gm cell provides for stabilization of the transconductance by compensating for manufacturing process variation of the value of the linearizing resistance RG by varying the transconductance bias current using a feedback signal proportional to the resistance of a resistor which is a replicate of the linearizing resistor.

    • A current and temperature compensated voltage reference circuit uses a power supply voltage as low as 1.3 Volts. A folded-cascode amplifier measures the temperature dependent voltages provided by first and second bias circuits, each including two series-coupled diodes or diode-connected bipolar junction transistors (BJTs), and provides a resulting proportional to absolute temperature (PTAT) current through a cascode-protected output transistor. A voltage reference circuit uses a PTAT current through a resistor to create a PTAT voltage in series with a diode-voltage. The resistor value is adjusted until the sum of these voltages is equal to the bandgap voltage of silicon, providing a temperature compensated voltage reference. The reference circuit is suitable for use with an implantable cardiac rhythm management system having a battery that provides a power supply voltage varying approximately between 1.3 Volts and 3.25 Volts. Cascode-protected current mirrors further improve rejection of such variations in the power supply voltage.
