摘要： In general, this disclosure describes techniques for reducing power consumption within an implantable medical device (IMD). An IMD implanted within a patient may have finite power resources that are intended to last several years. To promote device longevity, sensing and therapy circuits of the IMD are designed to incorporate an analog-to-digital converter (ADC) that provides relatively high resolution output at a relatively low operation frequency, and does so with relatively low power consumption. An ADC designed in accordance with the techniques described herein utilizes a quantizer that has a lower resolution than a digital-to-analog converter (DAC) used for negative feedback. Such a configuration provides the benefits of higher resolution DAC feedback without having the use high oversampling ratios that result in high power consumption. Also, the techniques avoid the use of, and the associated high power consumption of, a high resolution flash ADC, within the sigma delta loop.
摘要翻译：通常，本公开描述了用于降低可植入医疗装置（IMD）内的功率消耗的技术。植入患者体内的IMD可能具有有限的功率资源，这些功率资源将持续数年。为了促进设备使用寿命，IMD的感测和治疗电路被设计为包含在相对低的操作频率下提供相对高分辨率输出的模数转换器（ADC），并且以相对较低的功耗来实现。根据本文描述的技术设计的ADC利用具有比用于负反馈的数模转换器（DAC）更低的分辨率的量化器。这种配置提供了更高分辨率DAC反馈的优点，而不需要使用导致高功耗的高过采样比。此外，该技术避免了在Σ-Δ环路内使用高分辨率闪存ADC的相关高耗能。

摘要： This disclosure is directed to the synchronization of clocks of a secondary implantable medical device (IMD) to a clock of a primary IMD. The secondary IMD includes a communications clock. The communications clock may be synchronized based on at least one received communications pulse. The secondary IMD further includes a general purpose clock different than the communications clock. The general purpose clock may be synchronized based on at least one received power pulse. The communications clock may also be synchronized based on the at least one received power pulse.

摘要： 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.

摘要： Multi-chamber cardiac pacing systems for providing multi-site pacing to at least one of the right and left atria and then synchronously to the right and left ventricles in a triggered pacing sequence while providing for recharge of the output capacitors of each output amplifier in the shortest time. The recharge operations of the present invention come into play when bi-chamber pacing is invoked to deliver right and left heart chamber pacing pulses that are separated by a triggered pacing delay that overlaps, i.e., is shorter than, the recharge time period. In a truncated recharge mode, the first pacing pulse is delivered through the first pacing path, and the recharging of the first pacing path is commenced for the duration of the triggered pacing delay. Then, the second pacing pulse is delivered, and the second pacing path is recharged for a second recharge period. The recharging of the first pacing path is conducted simultaneously with or after completion of the second recharge period. In a postponed and sequential mode, recharging of the first pacing path is postponed until after delivery of the second pacing pulse and recharging of the second pacing path. In a simultaneous pacing mode, recharging of the first pacing path takes place after delivery of the second pacing pulse and simultaneously with recharging of the second pacing path.
