Hallo,
Would you please let me know how to look at the phase margin in TINA-TI simulation?
I found a material of TINA-TI simulation on the negative feedback.
There are some figures as below in this material.
Is it correct that how to look at the Phase margin and Gain margin is the blue arrow on the LoopGain curve?
Best Regards,
Kazu Ogawa
Like any engineering problem there is more than one way to get to the answer. My preferred way for loop gain analysis is documented in the 4 part Op Amp Stability tutorial available for download at:
Please read through the recommended material and it will teach you how to measure loop gain phase margin using TINA-TI. Thanks
