ABSTRACT:
A voltage converting circuit receiving an input voltage and an increased voltage and providing an output voltage higher than the input voltage at an output terminal, comprises a first pair of gate devices serially connected between the input voltage and a ground, a second pair of gate devices serially connected between the input voltage and the output terminal, a first capacitor connected between a node between the first pair of gate devices and a node between the second pair of gate devices for boosting the output voltage, a second capacitor connected between the output terminal and the ground for smoothing the output voltage, a control circuit for controlling said pairs of gate devices, and a pair of drivers for driving the second pair of gate devices respectively under the control of the control circuit. The pair of drivers are connected so as to operate between the increased voltage and the input voltage.
