Abstract: To provide a simple method for evaluating reliability of a transistor, a simple test which correlates with a bias-temperature stress test (BT test) is performed instead of the BT test. Specifically, a gate current value is measured in the state where a voltage lower than the threshold voltage of an n-channel transistor whose channel region includes an oxide semiconductor is applied between a gate and a source of the transistor and a potential applied to a drain is higher than a potential applied to the gate. The evaluation of the gate current value can be simply performed compared to the case where the BT test is performed; for example, it takes short time to measure the gate current value. That is, reliability of a semiconductor device including the transistor can be easily evaluated.

Abstract: When a portable electronic appliance is provided with two systems, a wireless power-feeding system and a wireless communication system, each system requires two power-receiving devices, a coil and an antenna, leading to a problem of increased electronic appliance size and cost. Wireless power feeding employs the resonance method and uses a resonance coil using the resonance method and a power-receiving coil that receives power from the resonance coil. At least one of the resonance coil and the power-receiving coil can also be used as an antenna for wireless communication. Thus, a power-receiving device that can be used for two systems, wireless power feeding and wireless communication, can be provided.

Abstract: A protection circuit is designed to operate when the level of a DC power supply potential which is generated in a rectifier circuit is equal to or greater than a predetermined level (a reference level), so as to decrease the level of the generated DC power supply potential. On the other hand, the protection circuit is designed not to operate when the DC power supply potential which is generated in the rectifier circuit is equal to or less than the predetermined level (the reference level), so as to use the generated DC power supply potential without change. A transistor of the protection circuit includes an oxide semiconductor layer, which enables a reduction in the off-state current of the transistor and a reduction in power consumption of the protection circuit.

Abstract: An object is to provide a photosensor utilizing an oxide semiconductor in which a refreshing operation is unnecessary, a semiconductor device provided with the photosensor, and a light measurement method utilizing the photosensor. It is found that a constant gate current can be obtained by applying a gate voltage in a pulsed manner to a transistor including a channel formed using an oxide semiconductor, and this is applied to a photosensor. Since a refreshing operation of the photosensor is unnecessary, it is possible to measure the illuminance of light with small power consumption through a high-speed and easy measurement procedure. A transistor utilizing an oxide semiconductor having a relatively high mobility, a small S value, and a small off-state current can form a photosensor; therefore, a multifunction semiconductor device can be obtained through a small number of steps.
