THD analysis of opamp

[rishabh_31ec]

Hi,
I have designed 4-stage Opamp in TSMC 180 nm process. Can anybody tell me how can I simulate for Total Harmonic Distortion (THD) of opamp in Cadence.

I've somewhere found this advice: View attachment Method_of_obtaining_THD_using_Cadence_waveform_calculator.pdf . Hope it's helpful.
