模拟电子  DAC技术用语 (D/A Converters Defini

Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...

PCB相关  PCB设计问题集锦

PCB设计问题集锦问：PCB图中各种字符往往容易叠加在一起，或者相距很近，当板子布得很密时，情况更加严重。当我用Verify Design进行检查时，会产生错误，但这种错误可以忽略。往往这种错误很多，有几百个，将其他更重要的错误淹没了，如何使Verify Design会略掉这种错误，或者在众多的错误中快速找到重要的错误。　　　答 ...

PCB相关  阻抗匹配

阻抗匹配　阻抗匹配（Impedance matching）是微波电子学里的一部分，主要用于传输线上，来达至所有高频的微波信号皆能传至负载点的目的，不会有信号反射回来源点，从而提升能源效益。　　大体上，阻抗匹配有两种，一种是透过改变阻抗力（lumped-circuit matching），另一种则是调整传输线的波长（transmission line matchi ...
