Abstract
Radio-frequency (RF) switch circuits are disclosed having one or more transistors coupled to provide improved switching performance. RF switches include at least one field-effect transistor (FET) disposed between first and second nodes, each the at least one FET having a respective body and a corresponding gate. A coupling circuit couples the respective body and corresponding gate of the at least one FET. The coupling circuit may include a diode in series with a resistor and may be configured to facilitate removal of excess charge from the respective body.
