Today’s circuit designers usually will need to design with analog circuitry on their boards, even if the core circuitry is Processor-based or a power supply design, MEMS/sensor or such. The problem is ...
在一些工艺中,除了 n-well 之外,还会提供 deep n-well (DNW) 层。DNW 的作用是将 NMOS 与 global p-substrate 进行隔离,从而使此 NMOS 能够工作在一个独立的 local p-substrate 上,此时 NMOS 的 bulk (B ...
NW.A.1 { @ Area >= 0.4 : 用一个大 NW 包住 PMOS 的小 NW NW.A.2 { @ Area of {OD2 OR {NW OR NT_N}}, {NW NOT OD2}, {OD2 NOT NW}, {OD2 AND NW} >= 0.4 : 上面的操作即可解决 WEL.A.1 { @ Area of {{{{{OD2 OR NW} OR NT_N} SIZING ...
