Abstract

An optimal method for testing a type of 8-bit digital to analog converters is presented. The method uses 89 out of 256 test vectors. The method for selecting the 89 vectors is explained. It is also pointed out that digital to analog converters of the type described in this paper are tested with 100% fault coverage with the 89 vectors. In addition, the 89 vectors also test for simultaneously switching errors (noise induced errors) and differential linearity. A discussion on the type of code which is used for designing this type of digital to analog converters which renders optimal testing (with 89 vectors) is included.

一种测试数模转换器的最佳方法

提出了一种测试8位数模转换器的最佳方法。该方法使用256个测试向量中的89个。说明了89个矢量的选择方法。文中还指出，本文所述类型的数模转换器用89个矢量进行了100%故障覆盖率的测试。此外，89个矢量还同时测试开关误差(噪声引起的误差)和微分线性。讨论了用于设计这种类型的数模转换器的代码类型，从而实现最佳测试(具有89个矢量)。
