Hello All, I'm a little confused about the parameter Kp (transconductance coefficient). For example the IRF9530 shows that this parameter is 5 A/V^2 but this value is usually given in books and in other places to be a lot smaller than this. Some of the ones I have seen are .25 mA/V^2. Is this the same value used in the equation for the drain current in saturation Id=Kp(Vgs-Vth)^2 ? Thanks. |

Have a look at Chapter : 11. The SPICE MOSFET Models Section: 11.1. DC Model in: http://www3.imperial.ac.uk/pls/portallive/docs/1/56133736.PDF (from this thread: https://www.circuitlab.com/forums/basic-electronics/topic/9dg62j8d/help-for-beginners-hobbyists/) |
