?Please how to make the phase -180?
Here it is in LTspice:someone kindly make this work on spice
God blessHere it is in LTspice:
Current source I1 injects a small current pulse into the loop (simulating normal circuit noise) to start the oscillations.
The frequency is 2Hz instead of the stated 1Hz.
Not sure why the sine and cosine signals have different amplitudes.
The sine output also has high distortion.
The values for R3, R5, and R7 (my designators) are unusually high for an op amp circuit.
Would suggest values at least an order of magnitude lower values for a real circuit (with corresponding adjustment of the associated capacitor values).

* The phase of an (ideal) inverting integrator is always +90deg. Any other statement is wrong. (Don`t blindly follow any book statements when they are obviously false).Also thought the output of integrator is +90 but book keeps it at -90. The 2nd order can give up to -180 given total of -270
1-st of all i was noting about my experience in compensating the LMx01/LMx08 for not the upper bandwidth edge operationabout high-frequency properties?
