Abstract:
A power amplifier amplifying an input signal is provided, comprising a power amplifier circuit, a bias circuit, and a compensation circuit. The power amplifier circuit has an input impedance responsive to the input signal, and amplifies the input signal to generate an output signal. The bias circuit is coupled to the power amplifier circuit, generates a DC bias signal to the power amplifier so that the power amplifier amplifies the input signal. The compensation circuit is coupled to the power amplifier circuit, provides a compensation impedance responsive to the input signal such that a combination of the input impedance and the compensation impedance is substantially constant regardless of the input signal.
