2 Threads found on edaboard.com: Split Transistor Layout
I am doing layout using cadence lately. As some transisitors in schematic are too large, I want to split one transistor into 4 or 5 pieces, not fold. Does anybody know how to do this or provide some related tutorial files? I searched a lot in google, but did not find something. Thanks!:D
You are describing a layout trick for large (wide) transistors. It is much easier to explain if you can see the picture. Essentially, for very large W the poly gate becomes fairly long and thus has a fair bit of resistance associated with since it poly is fairly high in ohms/sqare compared to metal. You split up the large (...)
