Systems, devices, and methods are provided for actively biasing a multi-stage amplifier. A method for differentially actively biasing a multi-stage amplifier comprises the steps of: actively biasing, with a single active bias circuit, an amplifier comprising a plurality of amplification stages; and differentially applying the bias provided by the single active bias circuit by biasing at least one amplification stage at a different bias level than another of the plurality of amplification stages. An active bias circuit for a multi-stage amplifier comprises: a single active bias circuit that is configured to actively bias a plurality of amplification stages via at least two gates; and a differential device configured to cause the active biasing provided to one gate to be different from the bias provided to another gate.
