| 20090079606 | IMPLANTABLE MEDICAL DEVICE WITH LOW POWER DELTA-SIGMA ANALOG-TO-DIGITAL CONVERTER - 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. | 03-26-2009 |
| 20090079607 | CHOPPER-STABILIZED ANALOG-TO-DIGITAL CONVERTER - This disclosure describes a chopper-stabilized sigma-delta analog-to-digital converter (ADC). The ADC is configured to provide accurate output at low frequency with relatively low power. The chopper-stabilized ADC substantially reduces or eliminates noise and offset from an output signal produced by the mixer amplifier. Dynamic limitations, i.e., glitching that result from chopper stabilization at low power are substantially eliminated or reduced through a combination of chopping at low impedance nodes within the mixer amplifier and feedback. The signal path of the ADC operates as a continuous time system, providing minimal aliasing of noise or external signals entering the signal pathway at the chop frequency or its harmonics. In this manner, the chopper-stabilized ADC can be used in a low power system, such as an implantable medical device (IMD), to provide a stable, low-noise output signal. | 03-26-2009 |

Other power management features may additionally or alternatively be employed. For instance, the device may send an uplink telemetry signal to an external device to request that recharge power be decreased. The device may switch additional resistance into the circuit of the coil to reduce the Q of the circuit. As another example, the device may clamp the circuit of the coil to ground. | 08-04-2011 |
