    摘要： A semiconductor device with a novel structure is provided. The semiconductor device includes a mixer circuit including a digital-analog converter circuit, a control circuit for controlling the digital-analog converter circuit, a power source control switch, and a plurality of Gilbert circuits. The plurality of Gilbert circuits each include an analog potential holding circuit for holding an analog potential output from the digital-analog converter circuit. The control circuit has a function of outputting a signal for controlling the analog potential holding circuit and the digital-analog converter circuit. The power source control switch has a function of stopping supply of a power source voltage to the control circuit in a period during which the analog potential held in the analog potential holding circuit is not updated. The analog potential holding circuit includes a first transistor. The first transistor includes a semiconductor layer including an oxide semiconductor in a channel formation region.

    摘要： A method for reducing power consumption of a source driver included in a display device and suppressing heat generation is provided. In a display device in which each pixel is supplied with a data signal of image data through a source line, a source driver is included, each source line is electrically connected to the source driver, and the source driver has a function of driving the source lines. In the case where the amount of change of the data signal of the image data is small, in other words, in the case where power for charging and discharging the source line can be small, the source driver reduces the apparent size of the transistor at the output stage, and power consumption can be reduced. Furthermore, the amount of heat generation can be reduced.

    摘要： An object is to provide an electronic device capable of recognizing a user's facial feature accurately. A glasses-type electronic device includes a first optical component, a second optical component, a frame, an imaging device, a feature extraction unit, and an emotion estimation unit. The frame is in contact with a side surface of the first optical component and a side surface of the second optical component. The imaging device is in contact with the frame and has a function of detecting part of a user's face. The feature extraction unit has a function of extracting a feature of the user's face from the detected part of the user's face. The emotion estimation unit has a function of estimating information on the user from the extracted feature.
