20110043676 | CMOS IMAGE SENSOR AND IMAGE SIGNAL DETECTING METHOD - A CMOS image sensor includes a photodiode, a switch configured to transfer a signal sensed by the photodiode to a sensing node, and a comparator electrically and directly connected to the sensing node and configured to compare the sensed signal of the sensing node and a ramp signal. Reset offset of the comparator is maintained at a constant offset voltage level during an initialization mode. | 02-24-2011 |
20120075000 | DRIVER AND HIGH VOLTAGE DRIVE CIRCUIT INCLUDING THE SAME - A high voltage drive circuit includes an edge detector for generating an edge detection signal by detecting edges of a first high side input signal and a first low side input signal, the edge detector providing a high side delay signal and a low side delay signal by delaying the first high side input signal and the first low side input signal, a dead time generator for generating a dead time signal indicating a preset dead time in response to the edge detection signal, and a driver comprising a drive signal generator for providing a high side output signal and a low side output signal by inserting the preset dead time based on the dead time signal into the high side delay signal and the low side delay signal. | 03-29-2012 |
20130300391 | CONTROLLER, CONTROLLING METHOD, AND DIGITAL DC-DC CONVERTER USING THE CONTROLLER AND THE CONTROLLING METHOD - An exemplary embodiment of the present invention generates a plurality of clock signals having a frequency according to an output voltage, a plurality of low clock signals of which frequencies are half of frequencies of the plurality of clock signals, and a phase signal corresponding to the output voltage by subtracting an average phase error from a count signal sampled by being synchronized with a reference clock signal from the count result of a first clock signal having the earliest phase among the plurality of clock signals. The average phase error is generated according to a comparison result of a first low clock signal corresponding to the first clock signal and each of other low clock signals among the plurality of low clock signals by being synchronized with the reference clock signal. | 11-14-2013 |
