Description of the Related Art. Technology by which a signal is transmitted and received without contact between media RF tags each incorporating an integrated circuit and an antenna RFID Radio Frequency Identification has been put to practical use in various fields and has been anticipated to further expand the market as a new mode of information communication. As the shape of an RF tag used for an RFID, a card shape or a chip shape which is smaller than such a card shape are employed in many cases however, various shapes can be employed in accordance with an application. As for RFID, communication between a reader, a readerwriter, or an interrogator and an RF tag can be performed with a radio wave. Diodes Incorporated is a leading global manufacturer and supplier of highquality application specific standard products. Specifically, a radio wave generated from an interrogator is converted into an electric signal by an antenna in an RF tag, and an integrated circuit in the RF tag is operated in accordance with the electric signal. Then, the radio wave modulated in accordance with an electric signal which is outputted from the integrated circuit is generated from the antenna thus, a signal can be transmitted to the interrogator without contact. Here, the interrogator also has an antenna. Note that RF tags can be broadly categorized into two types active RF tags and passive RF tags. An active RF tag incorporates a primary battery and does not generate electric energy in the RF tag. On the other hand, a passive RF tag can generate electric energy in the RF tag with the use of a radio wave generated from an interrogator. Specifically, after a radio wave received from the interrogator is converted into an AC voltage by an antenna, the AC voltage is rectified by a rectifier circuit and then supplied to each circuit in the RF tag as a power supply voltage by using a smoothing capacitor or the like. A structure of a rectifier circuit which uses one diode and a smoothing capacitor connected to an output side of the rectifier circuit is disclosed in Patent Document 1 Japanese Patent No. FIG. 1.

In the rectifier circuit illustrated in FIG. An anode and a cathode of the diode 8. In addition, one of two electrodes of a capacitor 8. GND. SUMMARY OF THE INVENTIONAs for RFID, intensity of a radio wave generated from an interrogator is prescribed by a standard such as ISO or JIS, or by decree. However, even when intensity of radio waves generated from an interrogator are constant, the shorter a communication distance between an RF tag and an interrogator is, the higher amplitude of a voltage of an AC signal received by an antenna in the RF tag is. When amplitude of the voltage of the AC signal that is received by the antenna is high, a voltage higher than a desired value is generated by a rectifier circuit, a smoothing capacitor, and the like that receive the signal first. The generated voltage is supplied to a circuit connected to a next stage of the rectifier circuit. Consequently, a voltage higher than a desired value is supplied to a semiconductor element in the circuit, and a current higher than expected flows through the semiconductor element. Therefore, there has been a problem in likeliness of deterioration or breakdown of the semiconductor element. When a radio wave generated from the interrogator includes noise, or radiation which is unnecessary is emitted from an electronic device other than the interrogator, the RF tag is exposed to an intense radio wave that exceeds a predetermined level. In this case, an AC signal which has such a high amplitude of voltage that deviates from a predetermined range is received by the antenna. When amplitude of the AC signal that is received by the antenna is high, a voltage higher than a desired value is generated by the rectifier circuit that receives the signal first. The generated voltage is supplied to a circuit connected to a next stage of the rectifier circuit. Consequently, a voltage higher than a desired value is supplied to a semiconductor element in the circuit, and a current higher than expected flows through the semiconductor element. Therefore, there has been a problem in likeliness of deterioration or breakdown of the semiconductor element. In addition, in order to reduce the cost of an integrated circuit, in general, the size of an integrated circuit formed of a semiconductor element is reduced by miniaturizing the semiconductor element and the number of integrated circuits that can be formed over one mother glass is increased. However, there is a problem that, when the semiconductor element is miniaturized, a withstand voltage gets low and thus an RF tag is more likely to be broken down due to excessive current. Moreover, an RF tag has another problem that, when a radio wave generated from the interrogator includes noise, a normal operation of a circuit in the RF tag is impeded by the noise. It is assumed that an AC signal which has a characteristic illustrated in FIG. A is inputted into the input terminal 8. FIG. 1. 8. In this case, as illustrated by a broken line in FIG. B, the AC signal inputted into the input terminal 8. The signal outputted to the output terminal 8. FIG. 1. 9B is outputted to the output terminal 8. FIG. 1. 9C illustrates temporal change of a voltage in the output terminal 8. FIG. 1. 9B, with the time scale increased. As illustrated in FIG. C, although periodic increase and decrease of voltage can be observed, an average of a voltage in each period is ideally kept the same, and the voltage of the signal outputted to the output terminal 8. DC voltage. However, when a radio wave generated from the interrogator includes noise, the noise is directly included also in a voltage generated by the rectifier circuit and the smoothing capacitor connected to an output side thereof. FIG. 1. 9D illustrates temporal change of a voltage in the output terminal 8. As illustrated in FIG. D, noise noise which has a low frequency wave occurs so that an average of a voltage in each period is increased and decreased with a longer period. When the voltage outputted from the rectifier circuit includes such noise illustrated in FIG. D, a DC voltage fluctuates over time thus, there is a possibility that an operation of a circuit of a next stage is adversely affected. In addition, FIG. E illustrates temporal change of a voltage in the output terminal 8. Since the signal illustrated in FIG. A includes a signal which has a higher frequency, noise with which voltage changes accidentally noise which has a high frequency wave occurs as illustrated in FIG. E. When the voltage outputted from the rectifier circuit includes such noise illustrated in FIG. E, similarly to the case where noise which has a low frequency wave occurs, a DC voltage fluctuates over time thus, there is a possibility that an operation of a circuit of a next stage is adversely affected.
