Abstract: A dynamic amplifier includes a first output capacitor, a first switch, a current source, a second switch, a voltage detector, a third switch and a level shifter. The first switch is coupled between a first terminal of the first output capacitor and a voltage detection node. The second switch is coupled to the current source and the voltage detection node. The voltage detector is coupled to the voltage detection node and the first switch. The third switch is coupled between the voltage detection node and a power source. The level shifter is coupled to a second terminal of the first output capacitor.
