摘要： The invention relates to an analog-to-digital converter comprising a reference voltage generating circuit, two coarse/fine comparators and two encoders for encoding the comparison result of the two coarse/fine comparators. In the invention, the two coarse/fine comparators processes a coarse comparison procedure and a fine comparison procedure on an input voltage in different clock cycle, thus, a sampling voltage error caused by an error of sampling time decreases. In another aspect of the invention, the capacitance of the input capacitor of the analog-to-digital converter decreases because the comparators for coarse comparison and fine comparison are the same, thus, a large power amplifier is not required for driving the input capacitor.
摘要翻译：本发明涉及一种模数转换器，包括参考电压发生电路，两个粗/精比较器和两个编码器，用于对两个粗/比较器的比较结果进行编码。在本发明中，两个粗/精比较器在不同的时钟周期内对输入电压进行粗略的比较程序和精细的比较程序，因此由采样时间的误差引起的采样电压误差降低。在本发明的另一方面，由于用于粗略比较和精细比较的比较器相同，因此模数转换器的输入电容器的电容减小，因此驱动输入电容器不需要大功率放大器。

摘要： A controller comprises an error comparator, a frequency generator, a pulse-width modulator and an output driver. The error comparator generates an error signal according to a feedback signal and a reference voltage. The frequency generator provides a frequency signal. The pulse-width modulator coupled to the error comparator and the frequency generator generates a pulse-width modulated signal according to the error signal and the frequency signal. The output driver coupled to the pulse-width modulator generates at least one switch signal according to the pulse-width modulated signal. Because the frequency signal is within at least one of the first predetermined bandwidths of the frequency range during a second predetermined time interval is within a third predetermined number, beat frequency interference is not detectable by users.

摘要： A load driving apparatus relating to light-emitting-diodes (LEDs) is provided. In the invention, a compensation voltage on a compensation pin (CMP) of a control chip would not be changed in response to (or with) the variation (i.e. enabling and disabling) of a pulse-width-modulation (PWM) signal for dimming. In other words, the compensation voltage on the compensation pin (CMP) of the control chip would be maintained in unchanging regardless of whether the PWM signal for dimming is enabled or disabled. Therefore, an LED string at the current switching transient does not have the generation of over-shoot current.
