Typical transistor design parameter [W/L]

  1. Oct 17, 2015 #1
    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?
