Abstract
Provided is a detector. The detector includes: one or more detection diodes configured to detect a change in an environment of a detection target; a Y capacitor including a plurality of capacitors separately disposed between one end of the detection diodes and a GND and between the other end of the detection diodes and the GND; and a rectifier circuit disposed at least between one end of the detection diodes and the GND or between the other end of the detection diodes and the GND, connected in series with the Y capacitor, and configured to transmit a common-mode current accompanying noise induced in the detection diodes to the GND and cut off a normal-mode loop current that flows between the plurality of capacitors and the detection diodes.
