20100033251 | OUTPUT STAGE CIRCUIT AND OPERATIONAL AMPLIFIER - An output stage circuit is disclosed, which includes a first PMOS transistor, a second PMOS transistor, a first NMOS transistor, and a second NMOS transistor. By using twin-well CMOS transistors and a specific circuit configuration, the invention supports a HALF AVDD structure, reduces power consumption and saves the cost of triple-well CMOS process. | 02-11-2010 |
20110084948 | LCD DRIVER CIRCUIT AND DRIVING METHOD THEREOF - An LCD driver circuit having a common electrode, a gate driving circuit and a source driving circuit is provided. The LCD driver circuit is applied to a display panel which has a plurality of pixels, a plurality of scan lines and a data line. The scan lines are divided into a plurality of scan line groups. The scan line groups are disposed on the display panel in a first sequence. The common electrode outputs a common voltage. The gate driving circuit is coupled to the scan lines and provides a control voltage to each scan line in a second sequence different from the first sequence. The source driving circuit is coupled to the data line to provide a gray level voltage to the data line. An area of the gray level voltage being higher or lower than the common voltage corresponds to a high level area of the control voltages in the nonadjacent scan line groups, and polarities of the operated pixels in the adjacent scan line groups are opposite. | 04-14-2011 |

20150162912 | LEVEL SHIFTER - A level shifter includes a first transistor, a second transistor, a third transistor, a fourth transistor, and a switching element. The first transistor is connected to a first node, the input signal and a first power supply voltage. The second transistor is connected to a second node, an inverted input signal and the first power supply voltage. The third transistor is connected to a second power supply voltage, the first node and the second node. The fourth transistor is connected to the second power supply voltage, the second node and the first node. The switching element is connected between the first node and the second node. When a voltage level of the input signal is changed, the switching element is turned on for a time interval according to the enabling signal, so that a voltage level of the output signal is changed. | 06-11-2015 |
