    摘要: Embodiments of methods and apparatus for receiving data are disclosed. More particularly, methods of receiving a current mode signal, which can improve a signal to noise ratio (SNR) according to a change in a power supply voltage, and current mode comparators and semiconductor devices that use the methods are provided. A method of receiving a current mode signal includes receiving a reference current signal and a data current signal through a channel and generating a sensing voltage based on a difference between the reference current signal and the data current signal, varying a transconductance to reduce an input resistance of the current mode comparator in inverse proportion to an increase in a power supply voltage supplied to the current mode comparator, and converting the sensing voltage into a CMOS level output signal using the current mode comparator.

    摘要: A source driver of a display panel includes a channel state signal generator, first switches, and second switches. The channel state signal generator generates first and second channel state signals that are each activated for a respective time period depending on adjustable state length data. The first switches are opened for uncoupling channel output signals from source lines of the display panel when the first channel state signal is activated. The second switches are closed for coupling together the source lines of the display panel for charge sharing when the second channel state signal is activated.
