摘要： A high resolution time detecting apparatus using interpolation and a time detecting method using the same are provided. The time detecting apparatus includes a delayer which generates delayed signals by sequentially delaying a reference signal using a plurality of delay elements, a latch unit which outputs latch signals using the delayed signals, and an interpolation unit which outputs interpolated signals using input and output signals of the delay elements. As a result, a high resolution TDC using an interpolation and a time detecting method using the same provide improved performance of digital PLL, high resolution digital signal output at a low power consumption, and controlled circuit size.

摘要： A digital frequency detector and a digital phase locked loop (PLL) are provided. The digital frequency detector includes a first conversion unit which outputs a first frequency as first frequency information of a digital type using a first ring oscillator that operates in a high-level period of the first frequency, a second conversion unit which outputs a second frequency as second frequency information of a digital type using a second ring oscillator that operates in a high-level period of the second frequency, and an operation unit which outputs a digital frequency for the first frequency by calculating a ratio of the first frequency information to the second frequency information.

摘要： A plasma display device and a method of driving the same, capable of reducing or preventing the deterioration of components such as a switching device, due to an overcurrent. In a reset period, in order to cause the voltage of a scan electrode to ramp down from a first voltage to a second voltage, a panel driver includes a falling ramp switch that repeats turn-on/turn-off operations, alternately coupling and de-coupling a low-level power supply to the scan electrode, resulting in a gradually falling ramp waveform. A switch controller generates a switching pulse to control the falling ramp switch. Each turn-on time of the switching pulse for the initial falling ramp waveform following a power-on of the plasma display device is controlled to be shorter than each turn-on time of the switching pulse for other falling ramp waveform.
