    摘要: A source driver of a display including a timing controller, the source driver and a display panel may include a digital-to-analog converter configured to output an analog value corresponding to a digital data signal supplied from the timing controller of the display panel. An amplification unit is configured to amplify the analog value in a switched capacitor mode to produce an amplified result, and to output the amplified result as a driving signal for driving a unit column line of the display panel. Therefore, since area and power consumption can be further reduced compared with a related source driver, costs can be reduced and Electromagnetic Interference (EMI) can be improved by the reduction of power consumption.

    摘要: An oscillator including a current bias circuit and a ring oscillator. The current bias circuit tracks a temperature change of the oscillator by using a control voltage and generates a plurality of bias voltages to supply a bias current according to the temperature change. The ring oscillator compares differential output signals generated according to the bias voltages and generates an oscillation signal as a result of the comparison.
