摘要： A current-mode data receiving device with sufficient fidelity for a display system. The receiving device includes: a current mirror, where an input current signal and a feedback current signal is received at a first terminal thereof and an output current signal with a current magnitude proportional to (e.g., equal to) the sum of the magnitudes of the input current signal and of the feedback current signal is output through a second terminal thereof; and a feedback unit that uses the magnitude of the output current signal as feedback to determined the magnitude and direction of the feedback current to the first terminal, and causes a decreases in the magnitude of the output current signal by a predetermined amount if the output current signal is at a high level, and increases the current magnitude of the output current signal by the predetermined amount if the magnitude of the output current signal is at a low level. Therefore, it is possible to correctly receive even a high-frequency signal and an irregular signal.

摘要： A gamma correction apparatus and methods thereof. The gamma correction apparatus may include at least one switching unit and a digital-to-analog converter, for example a capacitor digital-to-analog converter. The switching unit may transfer a first voltage to the digital-to-analog converter in response to a control signal. The digital-to-analog converter may generate a plurality of linear lines based at least in part on the first voltage to approximate a non-linear curve by generating a voltage transmission characteristic curve. A received digital signal may be converted into an analog signal based on the generated voltage transmission characteristic curve.
