    • PURPOSE: An ADC(Analog To Digital Converter) for processing wideband variable input signals is provided to adopt all WUXGA(Wide Ultra Extended Graphics Array) resolutions from VGA(Video Graphics Array) by applying a second stage reference voltage selection method to a flash ADC. CONSTITUTION: A SHA(Sample-And-Hold Amplifier)(110) exactly samples values which are suitable for necessary specification by using GBC(Gate-Bootstrapping Circuit). A MDAC(Multiplying Digital-To-Analog Converter)(120) reduces the necessary number of unit capacitors by half since a merged-capacitor switching technique is applied. A FLASH1 ADC(Analog To Digital Converter)(130) and a FLASH2 ADC(140) apply an interpolation method. An on-chip reference current voltage generator(150) processes a broadband variable input signal through one external signal. A clock generator(160) generates non-overlapped two clocks from one reference clock, which is inputted from the outside, in a chip. A digital correction circuit(170) including the clock generator and a divider is integrated with an on-chip.
    • 目的:提供用于处理宽带可变输入信号的ADC(模/数转换器),以通过将第二级参考电压选择方法应用于闪存ADC来采用VGA(视频图形阵列)中的所有WUXGA(Wide Ultra Extended Graphics Array) 。 构成:SHA(采样保持放大器)(110)通过使用GBC(栅极引导电路)精确地采样适合于必要规格的值。 使用合并电容切换技术,MDAC(乘法数模转换器)(120)将必需数量的单位电容器减少了一半。 FLASH1 ADC(模数转换器)(130)和FLASH2 ADC(140)应用插值方法。 片上参考电流电压发生器(150)通过一个外部信号处理宽带可变输入信号。 时钟发生器(160)从芯片中从外部输入的一个参考时钟产生非重叠的两个时钟。 包括时钟发生器和分频器的数字校正电路(170)与片上集成。
