Abstract
A method for improving an efficiency of a radio-frequency amplifier includes following steps. A set of predetermined parameters are set. A total circuit parameter is calculated according to the set of the predetermined parameters. A switch stress of a power switch is calculated according to the set of the predetermined parameters and the total circuit parameter. A first curve graph is made according to a duty cycle corresponding to the switch stress. The efficiency is calculated according to the set of the predetermined parameters and the total circuit parameter. A second curve graph is made according to the duty cycle corresponding to the efficiency of the radio-frequency amplifier. A value of the duty cycle is selected according to the first curve graph. The efficiency corresponding to the value of the duty cycle is obtained according to the second curve graph.
