Actual sizing in layout of transistors.

[Aravind_tucson]

I am a novice in this field. So please do bear with me if the qtn is stupid : ) ...
To increase the W/L ratio of a transistor we connect 2 transistors in parallel. if same W/L ratio's the resulting sizing would be 2(W/L). Am I right in this?
Similarly how can you achieve a increase in L sizing.

yes, you'r right. as for increasing length of MOS, you can connect the transistors in series.
in fact, put these transistors on a same active region to share the source/drain to save the area.
