ABSTRACT:
An analog-digital converter includes an analog switch on a semiconductor substrate, the analog switch having a P-channel transistor and an N-channel transistor; and a capacitive element having a first electrode and a second electrode. The first electrode and the second electrode are formed in a region in a layer different from a layer of the analog switch, the region extending over the analog switch. The first electrode and the second electrode have a comb-shaped pattern different from an arrangement pattern of the source regions and the drain regions of the P-channel transistor and the N-channel transistor.
