摘要
Disclosed is a CMOS power amplifier. A temperature compensation circuit of a CMOS power amplifier may include: a bias circuit unit supplying a gate bias voltage to a power amplification circuit part; a bias detection unit determining a class type of the power amplification circuit part according to the gate bias voltage; a temperature detection unit detecting a temperature-proportional voltage in proportion to ambient temperature; a temperature compensation control unit generating a compensation control value according to the temperature-proportion voltage in the class type determined by the bias detection unit; and a conversion unit converting the compensation control value of the temperature compensation control unit into a linear bias control value and providing the linear bias control value to the bias circuit unit, wherein the bias circuit unit compensates the gate bias voltage according to the linear bias control value of the conversion unit.
