Tool/software:
Hello TI support,
I am working on one circuit of TLV387 where in AOL analysis reveals circuit to be stable with PM=75' when AOL=0dB. However, at 27dB there seems to be lower PM=~ 45. Transient analysis looks to be stable. I will appreciate few queries,
1. In general any opamp circuit is stable or unstable when in between PM reduces to <30' while at AOL=0dB PM>=60' or so?
Details of the circuits & simulation results are attached below.
Regards,
JK
