    • Provided is a boosting voltage generating element used in a semiconductor integrated circuit, more particularly, is a charge pump. The charge pump includes a first converting unit and a second converting unit. The first converting unit is configured to receive a first voltage in response to a first clock signal to generate a first pumping voltage. The first converting unit is also configured to alternately output the first pumping voltage to a first terminal and a second terminal. The second converting unit is configured to receive the first pumping voltage through the first terminal or the second terminal in response to a second clock signal and a third clock signal respectively, to generate a second pumping voltage The second converting unit is also configured to provide the second pumping voltage to an output terminal. The second converting unit is configured to provide the second pumping voltage to the output terminal for at least half of a period of the second clock signal or the third clock signal.
    • 提供了一种用于半导体集成电路中的升压电压产生元件,更具体地,是电荷泵。 电荷泵包括第一转换单元和第二转换单元。 第一转换单元被配置为响应于第一时钟信号接收第一电压以产生第一泵浦电压。 第一转换单元还被配置为交替地将第一泵送电压输出到第一端子和第二端子。 第二转换单元被配置为响应于第二时钟信号和第三时钟信号分别接收通过第一端子或第二端子的第一泵浦电压,以产生第二泵浦电压。第二转换单元还被配置为提供 第二泵送电压到输出端子。 第二转换单元被配置为在第二时钟信号或第三时钟信号的周期的至少一半内向输出端提供第二泵浦电压。
