    Hi,

    I'm trying to measure input capacitance of simple inverter, and I have some problem...

    Using the following statement:

    .meas ac Cdb max(I(Vin0)/(2*3.1415*frequency))

    Result of this measure is ok, but it is in dB, and I don't know how to translate it to linear scale. I tried something like this:

    .meas ac Cin integ 20*log10(Cdb)

    but the result is wrong. Thanks in advance for help.

    Regards
