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 method and apparatus for driving a display panel in which a bus link between a timing controller and a source driver block is altered in order to simplify the structure of a circuit. The apparatus includes a timing controller to generate signals including data and a reference signal for driving the display panel at a display driving time. A plurality of source drivers generate signals for driving data lines of the display panel using the signals generated by the timing controller. First signal transmission means are provided for transmitting the data from the timing controller to each of the plurality of source drivers using a point-to-point connection link, and a bus for transmitting the reference signal generated by the timing controller to one of the plurality of source drivers. Also, second signal transmission means are provided for transmitting the reference signal between the plurality of source drivers using a serial cascade connection link.

A data transmission device may include a transmission chip, a plurality of reception chips and/or a pair of transmission lines. The transmission chip may transmit data and the reception chips may receive the data from the transmission chip. One of the plurality of reception chips may provide a corresponding terminal resistance when it receives the data. The transmission lines may be coupled between the transmission chip and the reception chips, and the transmission lines may have a daisy-chain configuration. Therefore, a data transmission device may provide a fixed terminal resistance in impedance matching and increase a transmission speed.
