A device for controlling the level of a transmission signal according to the channel loading is provided. The device may include a plurality of semiconductor devices and a controller to control the plurality of semiconductor devices. The controller may control the level of a signal to be transmitted to each of the plurality of semiconductor devices according to the channel loading on each semiconductor device.

Device for adjusting transmission signal level based on channel loading

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.

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.
