A waveform generator capable of generating a square wave and a ramp wave using one switching element is provided. A waveform generator includes a first transistor having a drain electrode, a gate electrode, and a source electrode. A first resistor and a first diode are coupled at a common node between a first input terminal and the gate electrode. A second resistor is coupled between the gate electrode and a second input terminal. A first capacitor is coupled between the drain electrode and the common node between the first resistor and the first diode.

Waveform generator and plasma display device using the same

A plasma display device includes first to fourth transistors and a plurality of first electrodes. A first terminal of a first capacitor is connected to a power supply supplying a voltage. A second terminal of a second capacitor connected to a second terminal of the first capacitor is connected to a ground terminal. A first diode is connected to the first electrodes through a first inductor and a fifth transistor, which forms a voltage rising path. A second diode is connected to the first electrodes through a second inductor and a sixth transistor, which forms a voltage falling path. A third diode is connected to the third transistor and the second diode, which forms a voltage sustaining path during a voltage rising period. A fourth diode is connected to the second transistor and the first diode, which forms a voltage sustaining path of a voltage falling period.
