Abstract: A signal may be arbitrarily delayed in discrete steps by an arbitrary delay buffer having an analog delay and a digital delay. An analog delay may have a number of selectable delay stages (e.g. ring oscillator with VCDL stages). A digital delay may have rising and falling edge detectors, resettable ring oscillators that oscillate in response to rising or falling edges and counters to count oscillations and generate rising and falling edge delay signals when oscillation counts reach rising and falling edge delay counts. A resettable ring oscillator may have a resettable stage (e.g. VCDL) that may be enabled and disabled. Selection of one or both digital and analog delays and respective delay times may be based on one or more characteristics. For example, an analog delay may delay an input signal or a delayed input signal received from the digital delay based on input signal frequency or total delay.

Abstract: A backlight module and a liquid crystal display (LCD) device thereof are proposed. The backlight module includes a DC/DC converter producing a positive/negative voltage level. The backlight module can output the positive and negative levels of driving voltage from an output end of the inverter to drive LEDs through alternately switching. Besides, a constant current can be obtained with designs of power on/off periods and energy-storing inductors to prevent LEDs employing current limiting resistors from having too low current efficiency and from being burnt out.
