ABSTRACT:
A driver circuit for generating a driving pulse signal having a plurality of levels using a supply voltage of a first polarization based on input timing signals. The driver circuit includes a circuit for generating a first voltage from the supply voltage; a first amplitude modulator for amplifying one of the input timing signals using the first voltage, thereby generating a modulated signal having levels of the first voltage and a grounded voltage; and a clamping circuit for clamping the modulated signal so as to shift the grounded voltage level of the modulated signal to a second voltage level having a second polarization opposite to the first polarization, thereby generating a pulse signal having the second voltage level and an amplitude substantially the same as that of the modulated signal.
