Abstract
A voltage boosting circuit and method thereof are capable of boosting an input voltage to a desired voltage while consuming a relatively small amount of power, in a highly efficient manner, and requiring a small number of circuit elements. A first switch of the voltage boosting circuit transfers the input voltage in response to a first control signal. A first charging/pumping portion charges the input voltage transferred from the first switch in response to a second control signal, adds the charged voltage to a first predetermined voltage in response to a third control signal, and pumps the addition result in response to the third control signal to provide a boosted voltage.
