【摘要】 以电荷泵锁相环为对象,提出了针对电荷泵锁相环各个模块的不同测试方法,着重论述了如何在一个完整的测试方案中把不同的测试方法结合起来——即采用电荷泵锁相环的全数字可测试性设计(D F T )法。这种测试方法简单、成本较低,具有较高的开发价值。更多还原

【Abstract】 This work puts forward different kinds of testing methods for different models of the charge pump phase-locked loop and strongly describes how to combine the various tests into a unified strategy-all-digital DFT(design-for-test) testing analysis for charge pump phase-locked loop. This kind of testing is simple and economical, so it is highly worth of investigating.更多还原
