CAPACITIVE LOAD DRIVING CIRCUIT AND PLASMA DISPLAY PANEL DEVICE, ESPECIALLY SUPPLYING PROPER OUTPUT VOLTAGE TO CAPACITIVE LOAD

摘要

PURPOSE: A capacitive load driving circuit and a plasma display panel device are provided to supply a proper output voltage to a capacitive load by reducing the variation of pulse width of an output signal generated when adjusting a delay time by a delay circuit. CONSTITUTION: The capacitive load driving circuit comprises an input port, and a front edge delay circuit(61-64) delaying a front edge of an input signal inputted from the input port. A back edge delay circuit(71-74) delays a back edge of the input signal. An amplification circuit(32,34) amplifies a driving control signal obtained through the front edge delay circuit and the back edge delay circuit. An output switch device(31,33) is driven by the amplification circuit.
