Abstract:
An integrated circuit device in which a 90-degree phase shifter is implemented, the 90-degree phase shifter including:a plurality of capacitors each being composed of a pair of electrodes, the pair of electrodes being arranged to be opposed to each other in a laminating direction; and a plurality of resistors each being composed of a pair of electrodes, the pair of electrodes being arranged to be opposed to each other with a resistance film sandwiched therebetween, wherein the capacitors and the resistors together form an input shifter and an output shifter that are cascaded, the capacitors constituting the input shifter and the capacitors constituting the output shifter are alternately arranged in a loop-shape array in plan view, and the resistors constituting the input shifter and the resistors constituting the output shifter are arranged inside the loop-shape array in radial symmetric relation.
