simulate a fully differential opamp

jacksonlu
I am a fresh ic designer, and now i am design an fully differential amplifier, but i don't know how to simulate it in spectre? such as dc gain, GBW, phase margin, CMFB stb, psrr, and so on. what are the testbenches for them? thanks!

    Hi, Andrew! thanks very much for your replay. May you tell me about the test benches for them, and how to do pz analysis? Should i break the feedback loop for pz simulation? and what about the feedback circuits for other simulations? BTW, does cadence has a tutorial or workshop about simulating an fully differential opamp? thanks very much!
