Abstract: A time-interleaved noise-shaping successive-approximation analog-to-digital converter (TI NS-SAR ADC) is shown. A first successive-approximation channel has a first set of successive-approximation registers, and a first coarse comparator operative to coarsely adjust the first set of successive-approximation registers. A second successive-approximation channel has a second set of successive-approximation registers, and a second coarse comparator operative to coarsely adjust the second set of successive-approximation registers. A fine comparator is provided to finely adjust the first set of successive-approximation registers and the second set of successive-approximation registers alternately. A noise-shaping circuit is provided to sample residues of the first and second successive-approximation channels for the fine comparator to finely adjust the first and second sets of successive-approximation registers.

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.
