    • In a PWM signal generation method of a voltage regulator, an output sense signal, a first ramp signal and a second ramp signal are provided. A first time point of the first ramp signal crossing with the output sense signal is used to determine a start point of an ON-time of a PWM signal, and a second time point of the second ramp signal crossing with the output sense signal is used to determine an end point of the ON-time of the PWM signal. Moreover, the first ramp signal is reset to a reference voltage at the first time point and then maintained at the reference voltage, and further ramps down starting from the end point of the ON-time. The second ramp signal ramps up starting from the start point of the ON-time, and then is reset to a preset voltage at the second time point.
    • 在电压调节器的PWM信号生成方法中,提供输出检测信号,第一斜坡信号和第二斜坡信号。 使用与输出感测信号交叉的第一斜坡信号的第一时间点来确定PWM信号的导通时间的起始点,并且使用与输出感测信号交叉的第二斜坡信号的第二时间点 以确定PWM信号的接通时间的终点。 此外,第一斜坡信号在第一时间点被复位到参考电压,然后保持在参考电压,并且进一步从导通时间的终点开始下降。 第二斜坡信号从接通时间的起点开始上升,然后在第二时间点被复位到预设电压。

    • An adaptive equalizer and operating method thereof are disclosed. The adaptive equalizer is oversampling-based. The adaptive equalizer includes a searching module, a compensation module, and an operating module. The searching module searches the equalizer setting from a lower compensation to a higher compensation to obtain a first equalizer setup value according a first monitored result of a monitor and then searches the equalizer setting from a higher compensation to a lower compensation to obtain a second equalizer setup value according to a second monitored result of the monitor. The operating module performs an operation on the first equalizer setup value and the second equalizer setup value to obtain an optimized equalizer setup value.

    • A source driver adapted to drive a plurality of data lines on a display panel is disclosed. The source driver includes a first output buffer, a second output buffer, a multiplexer, and a first regulating unit. The first and the second output buffers respectively enhance transmission intensities of a first and a second pixel signals. The first regulating unit regulates a slew rate of the first pixel signal outputted from the first output buffer to match a slew rate of the second pixel signal outputted from the second output buffer. The multiplexer coupled to the regulating unit selectively transmits the first and the second pixel signals to one of the odd data lines and one of the even data line, or to the one of the even data lines or the one of the odd data lines, according to a control signal.
