    • The present invention provides a charge-pump boosting circuit. In a charging period of a capacitor C1, a PMOS transistor Q1 and an NMOS transistor Q2 turn on, and the capacitor C1 is charged by voltage between a potential VCC and a potential VSS. On the other hand, in a discharging period of a boosting capacitor, a PMOS transistor Q3 and a PMOS transistor Q4 turn on, and charges accumulated in the boosting capacitor are discharged. In a discharging period of the capacitor C1, a selector SEL1 selects a terminal T1, and a feedback system, in which operation voltage applied to a gate of the PMOS transistor Q3 changes in accordance with fluctuations in output potential VDD2, is formed. At this time, only a resistance component of the PMOS transistor Q3 exists and no differential amplifier is provided, on a path of current flowing-into the capacitor C1 (between the potential VCC and a low voltage side terminal C1N of the boosting capacitor).
    • 本发明提供一种电荷泵升压电路。 在电容器C1的充电期间,PMOS晶体管Q1和NMOS晶体管Q2导通,电容器C1由电位VCC和电位VSS之间的电压充电。 另一方面,在升压电容器的放电期间,PMOS晶体管Q3和PMOS晶体管Q4导通,并且积蓄在升压电容器中的电荷被放电。 在电容器C1的放电期间,选择器SEL1选择端子T1,并且形成其中施加到PMOS晶体管Q3的栅极的工作电压根据输出电位VDD2的波动而变化的反馈系统。 此时,在流入电容器C1(电压VCC与升压电容器的低压侧端子C1N之间)的电流路径上,仅存在PMOS晶体管Q3的电阻成分,并且不设置差分放大器。
