CMOS POWER AMPLIFIER AND TEMPERATURE COMPENSATION CIRCUIT OF THE SAME

摘要

The present invention, Mr. Morse relates to a power amplifier, supplies the gate bias voltage of the power amplifier circuit bias circuitry; Bias detector to determine the class type of the power amplification circuit in accordance with the gate bias voltage; A temperature detector that detects a temperature proportional voltage proportional to the ambient temperature; In the class type is determined by the bias detector, temperature compensation controller for generating a compensation control value according to the temperature proportional voltage; And includes a transformation that provides the bias control circuit to convert the compensation value of the temperature compensation controller to control the linear bias value, the bias circuit is characterized in that to compensate for the gate bias voltage in accordance with said bias control value conversion portion The. ;
