Hi,
I have q question on the definition of CMOs level.
I noticed the definition of the CMOS level is deifferent from the different articles. E.g.,soem gives the Voh>4.7V and Vol<0.2V. While others gives the Voh>0.7VCC and Vol<0.3VCC. Moreover, I just saw a paper deifines Voh>0.9VCC and Vol<0.1Vcc.
May be it is because there are different modeling techniques, one might neglect some thing and the other might emphasize on it. What I know is that BSim is quite reliable.
