| 摘 要： | 模拟/数字转换器(ADC)是构成混合信号电路系统的基本器件。针对ADC测试中存在的问题,该文提出了一种新颖的使用斜坡信号作为测试激励的ADC内建自测试输出分析方法,相对于直方图分析方法,具有更短的测试时间,并且硬件资源开销较小。该方法除了可以测试ADC的差分非线性和积分非线性等静态参数,还可检测ADC的漏码特性。该文给出了两种完整的ADC内建自测试实现结构,可用于不同配置的混合信号电路系统。实验结果证明了所提出方法的有效性。

| Abstract: | A built-in self-test(BIST) scheme for analog to digital converters is proposed based on a linear ramp signal and efficient output analysis.The proposed analysis method is an alternative to histogram-based analysis techniques to provide test time improvements,especially when the resources are scarce.In addition to the measurement of DNL and INL,non-monotonic behavior can also be detected with the proposed technique.Two implementation options are presented based on how much on-chip resources are available.Exp... |
