    • an operational amplifier generates a power supply potential from a reference potential. An impedance adjuster adjusts an output impedance of the operational amplifier in accordance with a control signal. A charge accumulator accumulates an output charge of the operational amplifier whose impedance is adjusted by the impedance adjuster. A comparator compares an output voltage of the operational amplifier before the impedance adjustment by the impedance adjuster and the output voltage of the operational amplifier after the impedance adjustment by the impedance adjuster to each other, and the comparator further generates the control signal in accordance with a result of the comparison so as to output the generated control signal to the impedance adjuster.
    • 运算放大器从参考电位产生电源电位。 阻抗调节器根据控制信号调整运算放大器的输出阻抗。 电荷累加器累积运算放大器的输出电荷,其阻抗由阻抗调节器调节。 比较器在通过阻抗调节器进行的阻抗调整之后,将由阻抗调节器进行的阻抗调整之前的运算放大器的输出电压与运算放大器的输出电压进行比较,并且比较器进一步根据 比较结果,将所生成的控制信号输出到阻抗调节器。
