Designing with minimum L
Is it a good practice to design with minimum length? For example, with 0.25um technology, is it better to go with 0.25um or say 1um as length? I have designed a LVDS receiver and it seems to work better with 0.25um rather than 1um. Even the common mode range(0 - 2.4V) is unaffected (maybe since I am using a symmetrical OTA kind of structure with both nmos and pmos input transistors). I know there will be short channel effects with minimum length. What do you think are the other pros and cons? Any inputs on this would be appreciated.
Also when you say common mode voltage, it could either be a DC, AC or a combination of both I suppose. Please correct me if I am wrong.
Thanks.
