Semiconductor device
A semiconductor device with a high on-state current and high operating speed is provided. The semiconductor device includes a transistor and a first circuit. The transistor includes a first gate and a second gate, and the first gate and the second gate include a region where they overlap each other with a semiconductor layer therebetween. The first circuit includes a temperature sensor and a voltage control circuit. The temperature sensor has a function of obtaining temperature information and outputting the temperature information to the voltage control circuit. The voltage control circuit has a function of converting the temperature information into a control voltage. The first circuit applies the control voltage to the second gate.
