Pspice phase margin

WebAnalog Embedded processing Semiconductor company TI.com WebHi Kato, The model for the OPA1611 does model open loop gain and phase and output impedance of the OPA1611. In your design, the phase shift at Vout does not represent the phase margin of the circuit. You should instead measure the phase where feedback returns to the amplifier (the junction of R7, R5, L1, and C8), as Kai's post shows.
