RADIO-FREQUENCY SWITCH HAVING DYNAMIC BODY COUPLING |
| 摘要 |
Radio-frequency (RF) switch circuits are disclosed including at least one first field-effect transistor (FET) disposed between first and second nodes, each of the at least one first FET having a respective body and gate. The RF switch circuit may include a coupling circuit that couples the respective body and gate of the at least one first FET, the coupling circuit configured to be switchable between a resistive-coupling mode and a body-floating mode, as well as an adjustable-resistance circuit connected to either or both of the respective gate and body of the at least one FET, the adjustable-resistance circuit including a resistor in parallel with a bypass switch. |

1. A radio-frequency (RF) switch comprising:
at least one first field-effect transistor (FET) disposed between first and second nodes, each of the at least one first FET having a respective body and gate; a coupling circuit that couples the respective body and gate of the at least one first FET, the coupling circuit configured to be switchable between a resistive-coupling mode and a body-floating mode; and an adjustable-resistance circuit connected to either or both of the respective gate and body of the at least one FET, the adjustable-resistance circuit including a resistor in parallel with a bypass switch. |
