A driving signal generation circuit including a transforming circuit and a phase split circuit is disclosed. The transforming circuit is utilized to generate a transformed signal by delaying a rising or falling edge of each pulse of a pulse-width-modulation signal. The phase split circuit generates first and second driving signals by respectively extracting each odd pulse and each even pulse of the transformed signal. Furthermore, disclosed is another driving signal generation circuit including a phase split circuit and a phase shift circuit. The phase split circuit generates first and second push-pull signals by respectively extracting each odd pulse and each even pulse of the pulse-width-modulation signal. The phase shift circuit generates a driving signal by delaying rising and falling edges of each pulse of the first or second push-pull signal.
