ABSTRACT:
A high voltage generation circuit includes an inductor, a PN diode, a capacitor and a transistor. A high voltage sampling/division circuit, a control register, a voltage comparator, a counter, a pulse generation circuit and a ring oscillator in the high voltage generation circuit detect whether voltage generated through the capacitor is a desired high voltage or not and generates a pulse signal which controls ON/OFF of the transistor. Accordingly, a path of current flowing into the capacitor is changed and the generated voltage is digitally adjusted.
