Abstract
Charge pump and method therefor. For example, a charge pump for converting an input voltage to an output voltage includes: a first capacitor connected between a first terminal and a second terminal; a second capacitor connected between the second terminal and a third terminal; a first transistor including a first drain, a first source, and a first gate, the first drain being connected to an input terminal configured to receive the input voltage; a second transistor including a second drain, a second source, and a second gate; a third transistor; a fourth transistor; and an internal circuit configured to perform a self-detection process by determining whether or not at least one defect has been detected for at least one component selected from a group consisting of the first capacitor, the second capacitor, the first transistor, the second transistor, the third transistor, and the fourth transistor.
