发帖数: 10701 | 1 对呀。。因为single output 有Mirror pole， 这个是differential-in, single-outp
ut的缺点吧？
diff.in diff. out和diff.in,single out 复杂度来说，这个看你怎么看了。完全对称
的电路怎么会比不对称的复杂？
linearity? 当然diff.in. diff.out更好。
这些说起来，都是diff. in ..diff. out优于diff in. single-out.. |

发帖数: 10701 | 2 啥叫cmfb问题多多？
一个对称的电路，比起一个不对称的电路，哪个对common mode的变化处理的会更好些？
opamp大多会用来驱动下一级，这个opamp都有个differentinal 的input, 下面那集自然
也希望有个differenital的input, 意味着prefer这个opamp有个diff. output.
diff. in. diff. out的总体性能一定好与diff.in, single-ended out, 但一定是牺牲
了某样来获得diff. in, singled out.. |

发帖数: 402 | 3 控制面板上有两个buttons,1个是4WD diff lock，另一个是traction control (TRAC)
buttons. 请问什么时候该用哪个，它们之间的combination应该如何处理？Manual上说
如果在off-road或者陷在雪里，应该turn off TRAC control，以增加动力。但那个时
候难道我不应该按4WD diff lock按钮吗？有相关技术指南俺可以学习一下吗？谢谢。
谁能说一下什么情况该用哪个组合？confusing ...

atlas下运行svn diff提示svn: '.' is not a working copy
求教怎么用这个svn diff命令？在哪个目录下呢

diff是怎么比较两个文本文件的异同的呢？是通过hash table来实现的么？
如果不是hash table, 存不存在这种可能，通过shuffle一个文件的lines，使得前后两
次diff的结果不同？ |

发帖数: 10701 | 15 now.
nothing else but biasing
it is so easy for bisaing if taking diff. in. single ended out .
on the other hand, if taking full differential circuits, every cascode trans
istors will have to be biased by external voltage, or some ways.
the last chapter of Paul Grey's book is totally about the fully differential
circuits. we can see the full diff. is so much easy to understand. if the w
hole book are taught by the fully diffential , i guess it's much easier to l
earn. |
