PEAK VOLTAGE LIMITING CIRCUITS AND METHODS FOR POWER AMPLIFIERS |
| 摘要 |
Peak voltage limiting circuits and method for power amplifiers. A power amplifier and/or a voltage limiting circuit includes a diode circuit coupled to an output of an amplification stage, the diode circuit configured to provide a conductive path from the output when an output voltage exceeds a selected value. The power amplifier and/or voltage limiting circuit also includes a sink circuit coupled to the diode circuit and a bias circuit, the sink circuit configured to reduce a bias voltage provided by the bias circuit when the output voltage exceeds the selected value to thereby limit the output voltage. |

1. A voltage limiting circuit for a power amplifier (PA), comprising:
a diode circuit coupled to an output of an amplification stage, the diode circuit configured to provide a conductive path from the output when an output voltage exceeds a selected value; and a sink circuit coupled to the diode circuit and a bias circuit, the sink circuit configured to reduce a bias voltage provided by the bias circuit when the output voltage exceeds the selected value to thereby limit the output voltage. |
