    Opamp - Gain/Phase Margin Swept versus Variable

    Hello,

    I want to use Cadence Virtuoso/DFII to find the gain and phase margin of an opamp swept versus the load capacitance (or any other swept variable).

    So, Gain and Phase Margin on the Y axis, Load Capacitance on the X Axis.

    How would I go about constructing these plots ?

    Thank you.

    Re: Opamp - Gain/Phase Margin Swept versus Variable

    Do two parameters, frequency and capacitor, sweep in AC analysis.
    Then Use Skill language for postprocessing.

    This is same as https://www.edaboard.com/showthread.php?381490
