Abstract
A semiconductor device with a small circuit area and low power consumption is provided. The semiconductor device includes first to fourth cells, a current mirror circuit, and first to fourth wirings, and the first to fourth cells each include a first transistor, a second transistor, and a capacitor. In each of the first to fourth cells, a first terminal of the first transistor is electrically connected to a first terminal of the capacitor and a gate of the second transistor. The first wiring is electrically connected to first terminals of the second transistors in the first cell and the second cell, the second wiring is electrically connected to first terminals of the second transistors in the third cell and the fourth cell, the third wiring is electrically connected to second terminals of the capacitors in the first cell and the third cell, and the fourth wiring is electrically connected to second terminals of the capacitors in the second cell and the fourth cell. The current mirror circuit is electrically connected to the first wiring and the second wiring.
