    • PURPOSE: A successive approximation AD converter is provided to correct digital output errors, increase the region of the dynamic operation of a signal converter, and improve the noise ratio of outputted signals by including two bits with the same size of capacitance as LSB(Least Significant Bit). CONSTITUTION: A first converting column(100) includes a plurality of capacitors and is connected to a first input terminal of a comparator(200). A second converting column(150) has the same configuration as the first converting column. 8 capacitors are connected to the second input terminal of the comparator. The comparator outputs a high or low output voltage to an SAR(Successive Approximation Register) logic unit of a controller(300) according to the differential voltage between the voltage of the first input terminal and the voltage of the second input terminal. The controller sets the digital signal to high or low level to control the switch of the capacitor and provides the set signal to the switch.
    • 目的:提供逐次逼近AD转换器来校正数字输出误差,增加信号转换器的动态工作区域,并通过包含与LSB相同尺寸的两个位来提高输出信号的噪声比(最低有效值 位)。 构成:第一转换列(100)包括多个电容器,并连接到比较器(200)的第一输入端。 第二转化柱(150)具有与第一转化柱相同的构造。 8个电容器连接到比较器的第二个输入端。 比较器根据第一输入端子的电压与第二输入端子的电压之间的差分电压向控制器(300)的SAR(逐次近似寄存器)逻辑单元输出高或低的输出电压。 控制器将数字信号设置为高电平或低电平,以控制电容器的开关,并将设置信号提供给开关。

    • An algorithmic analog-to-digital converter is provided to minimize linearity restriction derived from a capacitor mismatch by adding two digital signals outputted through two different capacitors when one analog signal is inputted. An algorithmic analog-to-digital converter includes an SHA(Sample-and-Hold Amplifier)(10) sampling and holding an inputted analog voltage. Two flash ADCs(30) converts one inputted analog signal to two digital signals(n1,n2) through two different capacitor and outputs two digital signals. One MDAC(Multiplying Digital-to-Analog Converter)(50) amplifies a difference between an outputted voltage of the SHA and a reference voltage through two different capacitor according to the digital signal outputted from the flash ADC and outputs to the flash ADC again. A continuous multi-phase clock generating circuit(60) differentially outputs an operation clock frequency according to a required resolution.
