Abstract
The present invention relates to an output voltage controlling circuit in the negative charge pump which allows the output voltage of the negative charge pump to be controlled at a desired voltage level using a breakdown point of the PMOS transistor for high voltage by a PMOS transistor for high voltage connected between the output terminal of the negative charge pump and a reference voltage generation circuit.
