使用窗口比较器的模拟电路部分中的信号的片上评估的可能性已被证明，并简要总结。问题之一是比较器窗口的批间变化。一个自动窗口重新定位技术的详细说明，允许补偿窗口移位。沿着本技术的实现一起描述用于包括参考比较器和评估比较器的实现的组件。它示出，这种技术允许自动批量条件调整的评估比较器。此外，该技术可以向自动化测试设备提供批次特定信息，由于其诊断能力，该信息可以记录在测试结果中。
The possibility of using window comparators for the on-chip evaluation of signals in the analogue circuit part has been demonstrated and is shortly summarized. One of the problems is the lot-to-lot variation of the comparator window. An automatic window repositioning technique is detailed that allows to compensate the window shift. The components for the implementation comprising a reference comparator and the evaluation comparators are described along with the implementation of the technique. It is shown, that this technique allows the automatic lot condition adjustment of the evaluation comparators. Furthermore the technique can provide lot specific information to an automated test equipment that can be documented in the test results due to its diagnosis capability.
