Abstract
The invention provides a voltage doubler switched capacitor circuit capable of detecting short circuit of flying capacitor and a detection method thereof. The voltage doubler switched capacitor circuit provides a way to connect the flying capacitor in parallel to the charging path, and calculate whether it is charged to a predetermined voltage in the designed charging time interval, and then it can effectively detect whether the flying capacitor is short-circuited.
