Abstract: A metal-oxide-metal (MOM) capacitor is provided in the present invention. The MOM capacitor includes a capacitor element, wherein the capacitor element includes a first electrode and a second electrode. A projection of the first electrode includes a closed pattern in the vertical projection direction. A projection of the second electrode is surrounded by the closed pattern of the projection of the first electrode in the vertical projection direction.

Abstract: A bootstrap circuit including a receiving circuit, a switched capacitor module and a booting circuit is provided. The receiving circuit receives an input signal to selectively output an output signal according to a control signal. The switched capacitor module is coupled to the input signal, and is arranged for generating the control signal according to the input signal. The booting circuit is coupled to the receiving circuit, and is arranged for applying an initial voltage when the control signal starts to enable the transistor, to increase a voltage level of the control signal.
