许多ATE系统必须以极高的准确度测量关键参数,因为这类系统的准确度必须远高于它们所测试的器件。新式ATE系统要求百万分之一(ppm)的准确度,促使最新信号处理技术取得了突破性进展。这类系统的设计非常复杂,需要性能最高的集成电路组件。在ATE系统k中,ADC起到了关键作用,它将信号从模拟域转换到数字域,以进行数字信号处理。ADC的准确度和性能常常决定了系统的总体准确度和性能。本文讨论 Many ATE systems must measure key parameters with great accuracy because the accuracy of such systems must be much higher than the device they are testing. The new ATE system requires parts per million (ppm) accuracy, prompting a breakthrough in the latest signal processing technology. The design of such systems is complex and requires the highest performing integrated circuit components. In the ATE system k, the ADC plays a key role in converting signals from the analog domain to the digital domain for digital signal processing. The accuracy and performance of ADCs often determine the overall system accuracy and performance. This article discusses
