    cmos nor gate layout

    Hi all,

    Where can I find a basic CMOS NOR gate Layout picture?

    Any suggestions will be appreciated!
    Best regards,
    Davy

    cmos nor

    ok dude.. one which which u have to remember when u design CMOS circuit.

    NMOS and PMOS when arranged in series and parallel give different logic. so make sure you maintain the arrangement to achieve the logic.

    -------|----------|----------------|
    | Series | Parallel |
    -------|---------- |---------------|
    NMOS| AND | OR |
    -------|----------|----------------|
    PMOS | NAND | NOR |
    -------|----------|----------------|

    maintain and keep in mind this truth table :P (atleast a truth table like) arrangement when u want to design a CMOS circuit.

    with regards,
    arun

    cmos nor layout

    yes, for and(nand), nmos are in series, pmos are in parallel
    for or(nor) nmos are in parallel, pmos are in series
    in detail, you can read some book, such as
    Digital Integrated Circuits A Design Perspective(Senond Edition)

    Re: CMOS NOR gate's Layout?

    you'd better see the NOR standard cell in the lib of synposys
