  • Integrated circuits, liquid crystal display (LCD) drivers, and systems
    Patent number: 9628102
    Abstract: An integrated circuit includes a digital-to-analog converter (DAC) circuit including at least one first channel type digital-to-analog converter (DAC) and at least one second channel type DAC. The integrated circuit further includes a plurality of sample and hold (S/H) circuits, each of the plurality of S/H circuits being coupled with a single DAC of the DAC circuit. A number of the at least one first channel type DAC is different than a number of the at least one second channel type DAC.
    Type: Grant
    Filed: February 9, 2015
    Date of Patent: April 18, 2017
    Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.
    Inventors: Nang-Ping Tu, Fu-Lung Hsueh, Mingo Liu, I-Fey Wang
