Official abstract text for this publication.
Radio-frequency (RF) switch circuits are disclosed providing improved switching performance. An RF switch system includes at least one field-effect transistor (FET) disposed between a first node and a second node, each having a respective source, drain, gate, and body. The system includes a coupling circuit including a first path and a second path, the first path being between the respective source or the respective drain and the respective gate of the at least one FET, the second path being between the respective source or the respective drain and the respective body of the at least one FET. The coupling circuit may be configured to allow discharge of interface charge from either or both of the coupled gate and body.
Opening claim text (preview).
What is claimed is: 1. A radio-frequency (RF) switch comprising: a field-effect transistor (FET) disposed between first and second nodes, the FET having a body and a gate; and a coupling path connected between the body and gate, the coupling path including a resistor and a capacitor connected in series, such that the capacitor of the coupling path substantially blocks any and all DC current flow from the gate to the body and from the body to the gate. 2. Th…
