Claim 5:
6. A self-excited oscillation suppression method for the power amplifying circuit, is characterized in that: said method can be used in said self-excited oscillation suppression devices for the power amplifying circuits in claim 1, said method comprises:
acquiring a frequency adjustment target of the target pole frequency from said power amplifying circuit,
acquiring a speed adjustment target for the closing speed of the feedback gain curve from said feedback loop and the open-loop gain curve from said power amplifying circuit,
determining the first device parameter of each device in said first compensation circuit based on said frequency adjustment target,
determining the second device parameter of each device in said second compensation circuit based on said speed adjustment target,
using the first compensation circuit with said first device parameters and the second compensation circuit with said second device parameters to perform self-excited oscillation suppression to said power amplifying circuit.
