A charge compensation circuit for use in an analog-to-digital converter (ADC) includes at least one capacitor and at least one logic circuit. A first terminal of the capacitor is coupled to a reference voltage of the analog-to-digital converter. The logic circuit is configured to adjust a voltage at a second terminal of the capacitor according to a control signal. The control signal is determined according to at least one output bit from the analog-to-digital converter.

Charge compensation circuit and analog-to-digital converter with the same

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.
