Abstract: PURPOSE: A CMOS full-swing output driving circuit using an on-chip capacitor is provided to shorten a switching time and reduce switching noise by using charges of an on-chip capacitor. CONSTITUTION: A CMOS full-swing output driving circuit(300) is formed with an input portion(310), a capacitor charging/discharging portion(320), and a main driving portion(330). The input portion(310) receives an input signal(IN) and generates the first and the second driving signals(d,db). The first driving signal(d) is not inverted by the input signal(IN). The second driving signal(db) is inverted by the input signal(IN). The capacitor charging/discharging portion(320) receives the first and the second driving signals(d,db) and charges or discharges capacitors(C1,C2). The main driving portion(330) receives the first driving signal(d) from the input portion(310) and charges from the capacitor charging/discharging portion(320) and outputs an output signal(OUT) to an output terminal(OUT1).
