The symmetric ternary current-mode CMOS circuits designed by using this theory not only have simpler circuit structures and correct logic functions, but also can process two-way signal.
For the entire line, the number of branch circuit should not be too small, generally should be light to go all the way, air conditioning to take the two road, the outlet to go three to four.
对于整个线路来说，分支回路的数量也不应过少，一般应该是灯走一路、空调走二路、插座走三至四路。

Common always circuit design are two ways, one is internal clock way, another way to external clock way.
