The present invention discloses a circuit and method for generating a continuous pulse signal. The circuit of the present invention comprises: a PWM device generating a clock signal and a PWM signal, and a pulse continuity detector coupled to the PWM device. The pulse continuity detector further comprises: a positive pilot signal generator, a negative pilot signal and a multiplexer. The positive pilot signal generator is coupled to the PWM device to receive the clock signal and the PWM signal and then outputs a positive pilot signal. The negative pilot signal generator is coupled to the PWM device to receive the clock signal and the PWM signal and then outputs a negative pilot signal. The multiplexer is coupled to the PWM device, the positive pilot signal generator and the negative pilot signal generator to receive the PWM signal, the positive pilot signal and the negative pilot signal, and outputs the positive pilot signal or the negative pilot signal according to the PWM signal. Thus, the present invention can provide a continuous pulse signal and prevent the pulse signal from being interrupted.
