Abstract
Disclosed is a device capable of compensating for amplitude-modulation to phase-modulation distortion. The device includes a transmitter and a controller. The transmitter includes an amplifier circuit, a phase-shift adjustment circuit, and an output circuit. The amplifier circuit is configured to output an amplified signal according to an input signal. The phase-shift adjustment circuit, set between the amplifier circuit and the output circuit, includes at least one of an adjustable capacitor and an adjustable inductor and is configured to adjust the phase shift of the amplified signal according to a control signal. The output circuit is configured to output an output signal according to the amplified signal. The controller is configured to generate the control signal according to the input signal, in which the control signal varies with the input signal.
