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?
