1. A switching device comprising:

  • a field-effect transistor (FET) including a gate terminal;

    a negative bias circuit configured to generate a negative voltage signal at an output terminal of the negative bias circuit based on a radio frequency (RF) signal applied to the switching device; and

    a decoder circuit coupled with the output terminal of the negative bias circuit and the gate terminal, the decoder circuit configured to couple the output terminal of the negative bias circuit with the gate terminal when the FET is in an off state.
