Abstract: PURPOSE: A temperature compensation circuit and a device including the same are provided to always have constant operation characteristics regardless of the change of temperature by including the temperature compensation circuit. CONSTITUTION: A temperature compensation circuit(100) includes a voltage supply, a first transistor(101), a first current mirror(111), a first resistance(103) and a second resistance(104). The first transistor changes an output current in proportion to temperature. The first current mirror is connected to an output terminal of the first transistor and a current supply. The first resistance is connected between an output terminal of the first current mirror and a ground terminal. The first resistance controls the current flowing in the first current mirror.

Abstract: PURPOSE: An RFID tag having a secondary modulator is provided to allow a sub modulating unit to widen the range of impedance modification. CONSTITUTION: A main modulating unit(1109m) modulates impedance of an IC(11) according to a digital transmitting signal which is transmitted to an RFID(Radio Frequency ID) reader through an antenna. A sub modulating unit(1109s) modulates the range of impedance modification of the IC. The IC modulates an input signal from the antenna and a control unit and includes a modulating unit for supplying the modulated input signal to the control unit.
