Abstract: A timing generator includes a first current source, a first switch, a second current source, a second switch, a third switch, a capacitor, a signal synthesizer, and a timing difference extractor. The first current source is for generating a first current according to the input voltage. The second current source is for generating a second current according to the input voltage. The first switch includes a control terminal for receiving a charging signal. The second switch includes a control terminal for receiving a timing difference signal. The third switch includes a control terminal for receiving a reset signal. The capacitor is coupled between a charging terminal and a ground terminal. The signal synthesizer is for generating a timing signal according to a charging voltage and a reference voltage. The timing difference extractor is for generating a timing difference signal according to the timing signal and a deformed timing signal.
