| 20090039928 | LOW POWER AND LOW TIMING JITTER PHASE-LOCK LOOP AND METHOD - A phase-lock loop generates an output clock signal from an input clock signal. The output clock signal is coupled through a clock tree and is fed back to a phase detector, which compares the phase of the output clock signal to the phase of the input clock signal. The output clock signal is generated by a voltage controlled oscillator having a control input coupled to receive an output from the phase detector, and a frequency multiplier coupled to the output of the voltage controlled oscillator. As a result, the CLK | 02-12-2009 |
| 20090066379 | Delay Stage-Interweaved Analog DLL/PLL - A methodology is disclosed that enables the delay stages of an analog delay locked loop (DLL) or phase locked loop (PLL) to be programmed according to the operating condition, which may depend on the frequency of the input reference clock. The resulting optimized delay stages allow for a broad frequency range of operation, fast locking time over a wide range of input clock frequencies, and a lower current consumption at high clock frequencies. Better performance is achieved by allowing the number of analog delay stages active during a given operation to be flexibly set. The deactivation or turning off of unused delay stages conserves power at higher frequencies. The high frequency range of operation is increased by using a flexible number of delay stages for various input clock frequencies. Because of the rules governing abstracts, this abstract should not be used to construe the claims. | 03-12-2009 |

| 20080246695 | Plasma display and driving method thereof - In a plasma display and a driving method thereof, a sustain pulse of a high level voltage is supplied to a scan electrode or a sustain electrode during a sustain period using a capacitor charged to a voltage corresponding to a voltage difference between a high scan voltage and a low scan voltage. A low-voltage capacity transistor is connected between a power source and the scan electrode, the power source supplying a high level voltage to the scan electrode. Using the low-voltage capacity transistor results in reduced driving circuit costs and, in addition, the number of times that a transistor supplying the high scan voltage to the scan electrode and a transistor supplying the low scan voltage to the scan electrode is reduced, thereby reducing ElectroMagnetic Interference (EMI). | 10-09-2008 |
| 20090058841 | PLASMA DISPLAY AND DRIVING METHOD THEREOF - A plasma display and a method of driving the plasma display. The plasma display includes a plasma display panel including a plurality of discharge cells corresponding to sustain electrodes and scan electrodes. A first transistor is coupled between a first power source and a node coupled to the scan electrodes. A second transistor and a diode are coupled in series between a second power source and the node. The first and second transistors are alternately turned on during a sustain period, and the diode is configured to interrupt a current flowing from the second power source to the node. | 03-05-2009 |
