    how to get uncox

    can anyone tell me how to find the values of UnCox and the output resistance(ro) of the transistor(i.e. drain to source resistance)
    I am using a thin oxide transistor W=150nm and L=40nm

    uncox value

    Hiii

    U can watch all the parameters by simply clicking on the component after performimg simulation. This is according to simulator.

    If u want to calculate theoritically fix the W/L, Id, Vg and Vd and calculate µCox..


    Regards

    finding the value of UnCox in cadence spectre

    use dc analysis, un, eox, tox, weff, leff, gds are all there in results browser

    all the model parameters for different bsim versions are listed and described here:

    Get a basic transistor, have a very very very basic circuit, sweep the gate-source voltage and monitor the drain current
