Switching device with negative bias circuit

摘要

Embodiments provide a switching device including one or more field-effect transistors (FETs). In embodiments, a negative bias circuit is configured to generate a negative voltage signal based on a radio frequency (RF) signal applied to the circuit. When the FET is in an off state, the negative voltage signal is provided to a gate terminal of the FET.
