摘要： Provided is a compensation circuit capable of improving compensation precision for manufacturing variations. The compensation circuit includes a manufacturing variation detection circuit which detects manufacturing variation of a transistor based on a first voltage output from an output terminal of the transistor having an input terminal applied with a substantially constant first current to temperature or based on a second current output from an output terminal of the transistor having an input terminal applied with a substantially constant second voltage to temperature, and a voltage generation circuit which generates a supply voltage supplied to an electric circuit based on the manufacturing variation. The first current corresponds to the substantially constant second voltage to temperature, and the first voltage corresponds to the substantially constant second current to temperature.

摘要： A square detection circuit square-detects a portion of a high frequency transmission signal that is extracted by a directional coupler, of a high frequency transmission signal amplified by a power amplifier. A first adjustment circuit extracts a DC component from a detection output of the square detection circuit, and adjusts respective amplitudes of baseband I and Q signals generated by an I/Q signal generation circuit, in response to the extracted DC component. A second adjustment circuit extracts an AC component from the detection output of the square detection circuit, and adjusts the respective amplitudes and phases, and the respective DC offsets of the baseband I and Q signals generated by the I/Q signal generation circuit, in response to the extracted AC component.
