Use of highly integrated application specific circuits (ASICs) in bioelectric data acquisition systems promise important new insights into the origin of a large variety of health problems by providing light-weight, low-power, low-cost medical measurement devices that allow long-term studies. They also promise significant cost reduction in medical care, as patients in principle become mobile and do not have to be hospitalized for observation. We report on the development and successful implementation of a universal ASIC, designed to meet key characteristics of a broad variety of bioelectric signals in terms of their dynamic range, sampling rate and input referred noise; e.g. electrocardiogram (ECG), electroencephalogram (EEG) and, most constringently, evoked potentials (EPs). Our approach for the first time makes cost-effective use of state-of-the-art microelectronics in medical measurement equipment, thus offering to replace discrete, single application devices used at present.
在生物电数据采集系统中使用高度集成的专用集成电路（ASIC），有望通过提供轻便、低功耗、低成本的医疗测量设备，对各种健康问题的根源获得重要的新见解，这些设备可用于长期研究。它们还有望大幅降低医疗成本，因为原则上患者可以行动自如，无需住院观察。我们报告了一种通用ASIC的开发及成功应用，该ASIC旨在满足各种生物电信号在动态范围、采样率和输入参考噪声方面的关键特性；例如心电图（ECG）、脑电图（EEG），最具挑战性的是诱发电位（EP）。我们的方法首次在医疗测量设备中经济高效地利用了最先进的微电子技术，从而有望取代目前使用的离散式单用途设备。
