Abstract: PURPOSE: A high voltage charge pump circuit is provided to improve operating characteristic at low voltage and prevent an efficiency drop by threshold voltage. CONSTITUTION: A circuit generates internal high voltage from external input power voltage. The circuit comprises an oscillator (4-1), a first charge pump circuit (4-2), a level shifter (4-3), a second charge pump circuit (4-4), and a detector (4-5). The oscillator (4-1) is activated by an enable signal (OSCen) outputted from the detector (4-5), and generates a phi signal oscillating in uniform frequency. The first charge pump circuit (4-2) receives the phi signal from the oscillator (4-1) and generates high voltage (Vpp) to be supplied to the level shifter (4-3). The level shifter (4-3) receives the phi signal from the oscillator (4-1) and converts the phi signal into a clock signal pair oscillating between ground level and Vpp level. The second charge pump circuit (4-4) generates high voltage (Vout) by the clock signal pair. Since the first charge pump circuit (4-2) generates voltage (Vpp) higher than the external input power voltage and then supplies the high voltage to the second charge pump circuit (4-4), voltage operating characteristic is improved.
