    Dear All,

    How can I obtain the value of Gain-crossover frequency from a SPECTRE
    simulation. I was earlier using gainBwProd() for this purpose. But
    that would become inaccurate if more than one pole appears before the
    crossover frequency [as it simply calculates the (DC gain x dominant
    pole) ].

    Any help will be appreciated.

    Hi Samiran,

    You could use the cross() function to determine the point at which db20() of the
    gain crosses 0, say? Or the mag() crosses 1?
