<p><P>PROBLEM TO BE SOLVED: To provide a demodulation circuit having a sufficient demodulation ability or to provide an RFID tag which uses a demodulation circuit having a sufficient demodulation ability. <P>SOLUTION: A material which enables a reverse current to be small enough, for example, an oxide semiconductor material, which is a wide gap semiconductor, is used in part of a transistor included in a demodulation circuit. By using the semiconductor material which enables a reverse current of a transistor to be small enough, a sufficient demodulation ability can be secured even when an electromagnetic wave having a high amplitude is received. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
