Abstract: A compensator compensates for the distortions of a power amplifier circuit. A power amplifier neural network (PAN) is trained to model the power amplifier circuit using pre-determined input and output signal pairs that characterize the power amplifier circuit. Then a compensator is trained to pre-distort a signal received by the PAN. The compensator uses a neural network trained to optimize a loss between a compensator input and a PAN output, and the loss is calculated according to a multi-objective loss function that includes one or more time-domain loss function and one or more frequency-domain loss functions. The trained compensator performs signal compensation to thereby output a pre-distorted signal to the power amplifier circuit.

The intelligent pulse control circuit comprises a control unit, a buffer unit, a comparing unit and a switch unit. The buffer receives a loading signal. The comparing unit is coupled to the buffer unit, receives the loading signal generated according to the current of the output loading, and compares the loading signal and the feedback signal to generate a control signal. The switch unit is controlled by the control signal of the comparing unit to provide a turn-off signal. When the output loading is light load, the switch unit controls the control unit to disable the PFC stage and the PWM stage according to the turn-off signal. Accordingly, the intelligent pulse control circuit can reduce the power consumption when the output loading is light load.
