摘要： Objects of the invention are to provide a clock generation circuit and to provide a semiconductor device including the clock generation circuit. The clock generation circuit includes an edge detection circuit, a reference clock generation circuit, a reference clock counter circuit, and a frequency-divider circuit. The reference clock counter circuit is a circuit which outputs a counter value, which is obtained by counting the number of waves of a reference clock signal outputted from the reference clock generation circuit, in a period of time from when the edge detection circuit detects an edge of a signal which is externally inputted to the edge detection circuit to when the edge detection circuit detects the next edge, to the frequency-divider circuit. The frequency-divider circuit is a circuit which frequency-divides the reference clock signal based on the counter value.

摘要： The semiconductor device includes a plurality of photosensors arranged in matrix. The photosensors each include a photoelectric conversion element and an amplifier circuit. A backlight is turned on, an object to be detected is irradiated with light, and the photosensor in a p-th row performs the reset operation and the storage operation. After that, the backlight is turned off, and the photosensor in a (p+1)th row performs the reset operation and the storage operation. Then, the photosensors in all the rows sequentially perform the selection operation. A difference between output signals obtained from the photosensors in adjacent rows is obtained. Using the difference, a captured image of the object is generated and a region where the object exists is detected. The amplifier circuit includes a transistor for holding stored electric charge, in which a channel is formed in an oxide semiconductor layer.

摘要： To increase the light detection accuracy, a method for driving an input-output device that includes a first light unit, a second light unit, a display circuit, and Y light detection circuits (Y is a natural number of 2 or more) is proposed. The same light-detection control signal is input to the Y light detection circuits. In a frame period set by a display selection signal, the first light unit is lit by sequentially switching Z light-emitting diodes and emitting light, and the second light unit is lit by making the white light-emitting diode emit light when the first light unit is not lit. In a period when the second light unit is lit, Y pieces of data corresponding to the illuminance of light entering the Y light detection circuits are generated.

In the protection circuit of the display device, a thin film transistor is used in which an amorphous semiconductor layer, a microcrystalline semiconductor layer, a gate insulating layer which is in contact with the microcrystalline semiconductor layer, and a gate electrode layer overlap with each other. Since current drive capability of the microcrystalline semiconductor layer is high, the size of the transistor can be made small. In addition, the amorphous semiconductor layer is included, so that the withstand voltage can be improved. Here, the display device is a liquid crystal display device or a light-emitting device.

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： 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.
