    pi model

    hi all,

    I need to calculate a 2-pi model lumped circuit for an onchip capacitor and onchip transformer.

    Could you tell me a tutorial for 2-pi circuit or tell me a book to read ?

    thanks so much.

    two-port circuit

    Hello,

    You can generate a PI Model/equivalent circuit using Sonnet em Broadband spice extract from S parameters or EM structure...

    Description:
    In general, the model contains an inductor (in series with
    a resistor if using loss), a capacitor and a resistor (when using loss) connected in
    parallel from each port to ground. A similar parallel RLC network is also
    connected between each port. Therefore, a four-port circuit can contain more
    elements than a two-port circuit. Each inductor may also have a mutual inductance
    to any other inductor in the network. The figure below shows the most complex
    equivalent circuit possible for a two-port (mutual inductances not shown).

    They have free version which you can download & try
