摘要： In a case where an ASK method is used for a communication method between a semiconductor device and a reader/writer, the amplitude of a radio signal is changed by data transmitted from the semiconductor device to the reader/writer when data is not transmitted from the reader/writer to the semiconductor device. Therefore, in some cases, the semiconductor device mistakes data transmitted from the semiconductor device itself for data transmitted from the reader/writer to the semiconductor device. The semiconductor device includes an antenna circuit, a transmission circuit, a reception circuit, and an arithmetic processing circuit. The antenna circuit transmits and receives a radio signal. The transmission circuit outputs to the reception circuit a signal showing whether or not the antenna circuit is transmitting the radio signal.

摘要： A semiconductor device such as an RFID, which can easily generate a given stable potential, is provided. Circuits included in a semiconductor device are categorized depending on whether a given stable power source potential is necessary. A power source potential generated from a wireless signal received by an antenna with the use of the antenna and a rectifier circuit is supplied to a circuit which needs a given stable power source potential through a regulator. On the other hand, a power source potential generated by the rectifier circuit is supplied to a circuit other than the circuit which needs the arbitrary power source potential. Thus, a semiconductor device including a regulator circuit easily designed with a smaller layout can be provided, and the semiconductor device can easily generate a given stable power source potential.

摘要： A semiconductor device that has a simple peripheral circuit configuration, is unlikely to deteriorate due to repetitive data writing operations, and is used as a nonvolatile switch. Even when supply of a power supply voltage is stopped, data on a conduction state is held in a data retention portion connected to a thin film transistor including an oxide semiconductor layer having a channel formation region. The data retention portion is connected to a gate of a field-effect transistor in a current amplifier circuit (in which the field-effect transistor and a bipolar transistor are connected as a Darlington pair), and thus the conduction state is controlled without leaking charge in the data retention portion.
