    • A method of testing a successive comparison type analog/digital converter which incorporates a voltage comparator, a register for successive comparison and a digital/analog converter. A reference digital signal is inputted to the incorporated digital/analog comparator to be converted into an analog signal, while a digital signal corresponding to the reference digital signal is inputted to an externally provided reference digital/analog converter to be converted into an analog signal. Both analog signals thus produced are compared with each other through the incorporated voltage comparator to thereby determine conversion accuracy. A successive comparison type analog/digital converter suited for the test includes further a change-over switch for introducing the externally supplied digital signal to the incorporated digital/analog converter and a changeover switch for leading outwardly the output signal from the voltage comparator.
    • 一种测试连续比较型模拟/数字转换器的方法,其包括电压比较器,用于连续比较的寄存器和数字/模拟转换器。 参考数字信号被输入到并入的数字/模拟比较器,以转换为模拟信号,而与参考数字信号相对应的数字信号被输入到外部提供的参考数字/模拟转换器,以转换为模拟信号。 通过并入的电压比较器将由此产生的两个模拟信号彼此进行比较,从而确定转换精度。 适用于测试的连续比较型模/数转换器还包括用于将外部提供的数字信号引入到并入的数字/模拟转换器的转换开关和用于向外引导来自电压比较器的输出信号的转换开关。

    • A first error amplification circuit amplifies a difference between a predetermined reference voltage and a first detection voltage that corresponds to the output voltage of a DC/DC converter, so as to generate a second voltage. A voltage level judgment circuit generates a third voltage having a discrete level that corresponds to the amplitude of a first voltage. A multiplying/dividing circuit multiplies the first voltage by the second voltage, and divides the resulting product by the third voltage, so as to generate a fourth voltage. A comparator compares the fourth voltage with a second detection voltage that corresponds to a current that flows through a switching transistor included in the DC/DC comparator. A driving circuit turns on the switching transistor for each predetermined period, and turns off the switching transistor according to the output of the comparator every time the second detection voltage becomes higher than the fourth voltage.
    • 第一误差放大电路放大对应于DC / DC转换器的输出电压的预定参考电压和第一检测电压之间的差,以产生第二电压。 电压电平判断电路产生具有对应于第一电压的振幅的离散电平的第三电压。 乘法/除法电路将第一电压乘以第二电压,并将所得乘积除以第三电压,以产生第四电压。 比较器将第四电压与对应于流经包括在DC / DC比较器中的开关晶体管的电流相对应的第二检测电压进行比较。 驱动电路在每个预定周期中导通开关晶体管,并且每当第二检测电压变得高于第四电压时,根据比较器的输出关断开关晶体管。
