只PMOS和一只NMOS构成。我们知道,MOS晶体管应该是四端器件。但是,如果MOS晶体管的衬底和源极相连时,它就可以被看成三端器件。为了电路需要,在元器件中选择衬底没有和源极相连的MOS晶体管。在...在图3.11中的Pin添加方法是这样的,从该界面的Edit下拉菜单中找到AddPin/Port,点击它,就可以在图中增加Pin,如图3.12...

this is the reason why the symbol appears broken for an Enhancement Mode MOSFET. The P-Channel MOSFETs are calledPMOSand they are represented by the following symbols.
