Abstract:
A current compensation circuit for providing a current to an amplifier circuit includes a first amplifier, a first transistor and a first bias circuit. The first bias circuit provides a first bias current to the first amplifier. The current compensation circuit includes a power detection circuit, an operational amplifier circuit and a current-to-voltage converter. The power detection circuit detects and converts an input power or an output power of the first amplifier to a first detection voltage. The operational amplifier circuit generates a second detection voltage according to the first detection voltage and a calibration voltage. The current-to-voltage converter converts the second detection voltage to a compensation current. A first compensation current flows to the first amplifier through the first transistor according to the compensation current, such that the first amplifier is driven by the first bias current plus the first compensation current.
