Circuit Suggestion

I have a need to shift a Sine wave 120°, I thought I had a reference where it can be done with a Op-amp circuit but have not found it searching on the web. Thanks for any suggestions.

    Single, fixed frequency or multiple frequencies?

    Phil,
    Thanks for the reply I want to shift a single fixed frequency 120°. I found a few circuits online that I plan to bench test but none of them really explain how its done.

    Since it's a single, fixed frequency, an analog delay line will do what you need. Just divide the signal's period by three to get the delay amount.

    Phil,
    Thanks I looked into analog delay lines and a came across a few examples that I will test.
