What is the difference between pmos, pmoshiv, pmos3, and pmostie in Cadence gpdk018?

SimbaG

Hello,

I am using gpdk018 to simulate my design and found that there are three or four different types of mosfet.

Could you let me know that what is the difference between pmos, pmoshiv, pmos3, and pmostie in Cadence gpdk018?

Thank you for your help.

    First of all, there is no "gpdk018". Perhaps you mean gpdk180?

    Secondly, in gpdk180 there is nothing called "pmoshiv" or "pmostie".  There are four pmos transistor symbols:

    • pmos
    • pmos3
    • pmoshv
    • pmos3hv

    The pmos and pmos3 are the "low voltage" transistor - the difference between them is that pmos3 is a three-terminal symbol rather than having an explicit bulk pin. The pmoshv/pmos3hv are a similar pair, but for a high voltage transistor.

    These are in the gpdk_v3.3 from http://pdk.cadence.com - perhaps you're talking about some non-Cadence-supplied library from elsewhere - if so, perhaps you can give a reference?

    Regards,

    Andrew

    Sorry for inaccurate description, I am talking gpdk180 from Cadence.

    Lat me see pdk.cadence.com

    Thank you
