    hspice ac simulation

    Hello All,
    We use pac to analyze the ac response of switch cap circuits in spectre. Is there any
    way to analyze ac-response of switch caps in spice ?
    Best Regards,
    Sumit

    Yes, it´s possible with SPICE.
    For this purpose you have to replace each S/C unit with a time continuous analogon.
    There are specific tables how the different switch arrangements are replaced.
    The analog replacements can be modelled with delay lines or controlled sources.
    The procedure is described, for example, in
    Ghausi/Laker: Modern Filter Design - Active RC and Switched Capacitor.
