    Hi,

    Can anyone suggest me a test circuit for measuring open loop gain in shunt regulator?

    If you post a schematic, maybe we can try.

    Are you working with a discrete design, or some IC?

    Need a schematic

    Second page of this app note shows a typical method of measuring loop gain. You have to open the feedback loop and inject a signal. It takes a calibrated network analyzer.
