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: A transmission leakage signal removing apparatus and method thereof are provided to simply remove a leakage signal on all frequency bands in an RFID(Radio Frequency IDentification) system. CONSTITUTION: A circulator(110) applies a second transmission leakage signal which is reflected from an antenna of a first transmission leakage signal which is leaked from a transmission signal. A removing unit(130) generates a removing signal having a first transmission leakage signal and a second transmission leakage signal through the transmission signal. A phase controller(140) controls the phase of the first transmission leakage signal and the second transmission leakage signal. The phase controller generates a phase control leakage signal having a phase of the removing signal.

Abstract: PURPOSE: An apparatus for removing a transmission leakage signal is provided to improve a recognition rate of a tag by using a real time adaptive method for the removal of a transmission leakage signal. CONSTITUTION: A circulator(110) connects an antenna including a phase control offset unit(130) to a transmission path and a reception path. A removing unit(150) outputs a leakage removing signal(30) to the reception path. The leakage removing signal has the same as first and second transmission leakage signals(10,20) and includes a phase signal opposite to the first and second transmission leakage signals. The first transmission leakage signal is generated in the transmission path, and the second transmission leakage signal is reflected from the antenna.
