    Probe MOSFET Cgs and Cgd current in transient simulation Reply

    Is there any method to probe the current flowing through the Cgs and Cgd of a MOSFET?

    I just know I can click the node of the gate of MOSFET symbol in ADE to probe the gate current.  How can I access the Cgs and Cgd current?

    Thanks

    No, you can't save currents through internal parts of the model. Why would you want to anyway?

    Regards,

    Thanks for reply Andrew :)

    I want it because I want to get the Cgs and Cgd current to calculate the Qgs and Qgd.  They are important parameters for me to design the size of MOSFET for a switching regulator.
