I simulated an op amp of AD8139 in multisim, found there is a nonlinear fluctuation in op power supply, and the output is proportional to the input signal. So I want to analyses this reason of nonlinear fluctuation,could you offer me a Schematic Diagram of AD8139 since there is no detailed schematic diagram in the existing manual of AD8139, if you are not convenient to provide the internal schematic diagram, please explain to me in detail why the power supply fluctuation occurs.
