    i need some ideas on how to go about measuring the capacitance of a p-n
    juction of an off-the-shelf diode. i already have a suitabe DC voltage
    source to supply the diode with, a bunch of inductors, and an oscilloscope
    to find resonant frequency. thanks

    Most diodes have a junction capacitance listed in the datasheet. Look for the value "Cj"

    Hope that helps,
