摘要： A voltage generator with reduced noise features a detector, a controller, a sub-booster, a main booster and a voltage adder. The detector receives an output voltage, a first reference voltage and a second reference voltage lower than the first reference voltage, and then outputs a first sensing signal and a second sensing signal. The controller receives the first sensing signal and the second sensing signal and an action signal to output a first control signal and a second control signal. The sub-booster boosts a voltage in response of the first control signal. The main booster boosts a voltage in response to the second control signal. The voltage adder adds output signals from the sub-booster and main booster, to provide the output voltage.

摘要： The present invention relates to a pumping voltage generator configured to effectively generate a pumping voltage VPP depending on voltage variation. The pumping voltage generator of the present invention comprises a detector, a cycle selecting unit, an oscillator, a control driver and a pumping unit. The detector detects a plurality of pumping voltage levels, and outputs a plurality of enable signals in response to the detected voltage levels. The cycle selecting unit outputs an oscillation cycle selecting signal for controlling an oscillation cycle of a pumping voltage in response to the plurality of enable signals. The oscillator enabled by one of the plurality of enable signals outputs an oscillation signal corresponding to the oscillation cycle selecting signal. The control driver outputs a pumping control signal for controlling the pumping operation in response to the oscillation signal. The pumping unit outputs the pumping voltage in response to the pumping control signal.
