    Abstract: 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.

    Abstract: A power-up detection apparatus comprises a voltage divider, a potential detector and a buffer. The voltage divider divides an inputted power voltage in a predetermined ratio. The potential detector compares a predetermined potential with a potential outputted from said voltage divider, and outputs the comparison result. The buffer changes the level of said comparison result when said comparison result outputted from said potential detector is maintained at a predetermined potential for a predetermined period. As a result, a semiconductor device can be stably initialized because a power-up signal is generated only when an externally inputted power voltage is maintained at a current state over a predetermined period although the state of the external power voltage is toggled by noise.
