A power amplifier clipping circuit for minimizing output distortion is provided to suppress a rapid change of the output waveform without adding a capacitor when the output waveform is clipped by excessive input voltage, and to match the output waveform with the original waveform after the excessive input voltage is applied. The power includes an input voltage divider, two bias transistors connected to a positive voltage source, a third bias transistor connected to the first bias transistor and a first differential amplifier, a first current source connected to the third bias transistor and a negative voltage source and the first differential amplifier, fourth and fifth bias transistors connected to a negative voltage source and a second differential amplifier, a sixth bias transistor connected to the fourth bias transistor and the second differential amplifier, a second current source connected to the sixth bias transistor and a positive voltage source, a first output voltage controller connected between the negative voltage source and an output with a serial input resistor, and a second output voltage controller connected between the positive voltage source and the output and power amplifier. |
