  • Publication number: 20210272525
    Abstract: A source driver and a display device including the same, capable of accurately sensing pixels characteristics and characteristics of the source driver. A source driver includes a switch circuit configured to transfer first pixel signals or reference signals; first sensing channels configured to sense and hold the first pixel signals or the reference signals transferred from the switch circuit; second sensing channels configured to sense and hold second pixel signals; and a selection circuit configured to output a sampling signal by selecting the first pixel signals of the first sensing channels and the second pixel signals of the second sensing channels, and thereafter, output the sampling signal by selecting the reference signals of the first sensing channels.

  • Patent number: 9520892
    Abstract: Disclosed herein is a digital-to-analog converter (DAC) including a clock driver for controlling a clock signal to provide an inverse delay clock signal to allow at least selective adjustment of a return to zero (RZ) section; and a DAC core comprising at least two DAC units for receiving a digital input value, the clock signal and the inverse delay clock signal and providing an analog output value. According to the present invention, distortion of the output of the DAC may be attenuated and loss of the output may be minimized by utilizing the RZ technique.

  • Patent number: 8390382
    Abstract: There is provided a power amplifier circuit capable of improving cross isolation between a high frequency band power coupler and a low frequency band power coupler, by directly transmitting power to the high frequency band power coupler and the low frequency band power coupler from a power amplifier, and forming a predetermined inductance circuit or an LC resonance circuit in a line transmitting the power to the high frequency band power coupler. The power amplifier circuit may include a power amplifying unit supplied with power from the outside and amplifying an input signal, a coupling unit having a high frequency band power coupler and a low frequency band power coupler, and an isolation unit including a first power line and a second power line, wherein the first power line has an inductor blocking signal interference generated in a predetermined frequency band.
