Abstract: A radio frequency (RF) power amplifier with no reference voltage for biasing is disclosed. The RF power amplifier includes a three-terminal current source circuit, a current mirror circuit and an output-stage circuit. The three-terminal current source circuit receives a first system voltage and accordingly outputs a first current and a second current, and a source voltage exists between a first output terminal of the first current and a second output terminal of the second current. The current mirror circuit receives the first current and the second current and accordingly generates a bias current. The output-stage circuit receives the bias current so as to work at an operation point. The RF power amplifier utilizes the source voltage of the three-terminal current source circuit so the first system voltage is between a first voltage and a second voltage, and then the output-stage circuit outputs an output current which does not vary with a deviation of the first system voltage also with temperature compensation.
