Title:
電子機器
Document Type and Number:
Japanese Patent JP7179740
Kind Code:
B2
Abstract:
An electronic device including a semiconductor device capable of intermittent driving is provided. The electronic device includes a semiconductor device, and the semiconductor device includes a current mirror circuit, a bias circuit, and first to third transistors. The current mirror circuit includes a first output terminal and a second output terminal, and the current mirror circuit is electrically connected to a power supply line through the first transistor. The current mirror circuit has a function of outputting current corresponding to a potential of the first output terminal from the first output terminal and the second output terminal. The bias circuit includes a current source circuit and a current sink circuit, the current source circuit is electrically connected to the second output terminal through the second transistor, and the current sink circuit is electrically connected to the second output terminal through the third transistor. Switching on/off states of the first to third transistors achieves intermittent driving of the semiconductor device.
