1. An amplifier system, comprising:

  • a first amplifier having an input signal terminal and an output signal terminal;

    a second amplifier having an input signal terminal and an output signal terminal, wherein the input signal terminal is coupled to the output signal terminal of the first amplifier; and

    a phase noise suppression circuit having first and second input terminals and an output terminal, wherein the first input terminal is coupled to the input signal terminal of the first amplifier, the second input terminal is coupled to the output signal terminal of the second amplifier, and the output terminal is coupled to the first amplifier; and

    a supplemental noise suppression circuit having first and second input terminals, wherein the first terminal is coupled to the input signal terminal of the first amplifier and the second input terminal is coupled to the output signal terminal of the second amplifier.
