摘要： A boost circuit, such as might be used to generate a boosted voltage in an integrated circuit device (e.g., an EEPROM), includes a plurality of charge pump circuits having outputs connected in common and that generate current pulses responsive to respective phased periodic signals. The boost circuit further includes a multi-phase periodic signal generator circuit that generates the phased periodic signals such that they have respective different phases. For example, the multi-phase periodic signal generator circuit may include a control signal generator circuit that produces a control signal responsive to a voltage produced by the plurality of charge pump circuits, and an oscillator circuit that generates the plurality of phased periodic signals responsive to the control signal. Related operating methods are described.
