    • Disclosed is a printed circuit board (PCB) comprising at least one light emitting diode (LED) element and a PCB body. The LED comprises a heat sink, a light emitting body and two base feet, each base foot comprising a support portion for supporting the light emitting body, an engaging portion and a connecting portion for connecting the support portion to the engaging portion, and the heat sink is disposed under the support portion. The PCB body comprises a first recess portion for disposing the heat sink to increase heat dissipation of the heat sink and two second recess portions for receiving the engaging portions of the base feet to increase heat dissipation of the base feet.

    • The present inventive concept relates to an analog-digital converter. The analog-digital converter includes a clock generating unit generating a clock signal; a clock delay adjusting unit outputting one of a first clock signal to a Kth clock signal according to a control signal; a capacitive digital-analog converting unit outputting a difference between the analog signal and a reference signal; a comparison unit judging whether an output of the capacitive digital-analog converting unit is 0, a positive number, or a negative number, in response to an output of the clock delay adjusting unit; and an SAR logic unit transferring an output of the comparison unit to the capacitive digital-analog converting unit in response to an output of the clock delay adjusting unit and performing a successive approximation operation to output the N-bit digital signal.
    • 本发明构思涉及一种模数转换器。 模拟数字转换器包括产生时钟信号的时钟产生单元; 时钟延迟调整单元,根据控制信号将第一时钟信号中的一个输出到第K个时钟信号; 输出模拟信号和参考信号之间的差的电容数字 - 模拟转换单元; 比较单元,响应于时钟延迟调整单元的输出,判定电容数字 - 模拟转换单元的输出是0,正数还是负数; 以及SAR逻辑单元,响应于时钟延迟调整单元的输出,将比较单元的输出传送到电容数字 - 模拟转换单元,并执行逐次逼近操作以输出N位数字信号。
