Typical transistor design parameter [W/L]

[beyondlight]

I would like to know a typical W/L value for a MOSFET transistor.

L = channel length
W = channel width/transistor width

I am currently designing L to be L = 0.0001 cm for a transistor.

Cox = 5nF
mobility 1155 cm^2/Vs
K = 0.583 mA/V^2

This gives W = 20 cm. But this is way to large for a single transistor and W/L = 200,000 roughly.

I guess W and L should be about the same for one transistor?

Hi beyondlight. What is the range of W/L values you've come across in your web search for this detail?
