Pulse width modulation signal generator
A plus width modulation (PWM) signal generator is disclosed. The PWM signal generator includes a first signal generator providing a first signal, an output terminal, a first voltage generating circuit including connected to the first voltage generating circuit for providing a first present voltage according to the first signal, and a second voltage generating circuit connected to the first signal generator for providing a second present voltage according to the first signal. The first present voltage is earlier supplied to the output terminal than the second preset voltage, and after the first preset voltage continuously is provided for a period of preset time, the first voltage generating circuit stops providing the first preset voltage.
