    Hello,

    I simulated my VCO with a PSS simulation by varying the control
    voltage in order to draw the oscillation frequecy curve according to
    the control voltage.
    But to extract the value of Kvco, I need to determine the value of the
    slope of this curve at one point.

    You know how to draw (or calculate) the slope with the 'Calculator' of
    'WaveScan' (Cadence)

    Thank you for your help,

    Firas.

    just draw de derivative of the curve (select and add trace w/ the
    'Calculator') and pick the slope by means of evaluating the value of
    the dv/dt at a given interest point.

    Regards,
    Dionísio.
