ELECTRONIC DEVICE |
| 摘要 |
According to one embodiment, an electronic device includes a variable capacitor includes first and second electrodes, and indicating a first state in which a distance between the first and second electrodes is a first distance and a second state in which the distance between the first and second electrodes is a second distance shorter than the first distance, in accordance with a voltage applied between the first and second electrodes, a voltage applying circuit applying a voltage between the first and second electrodes, and a voltage detecting circuit detecting a first voltage based on an interelectrode voltage between the first and second electrodes. The variable capacitor, the voltage applying circuit and the voltage detecting circuit are provided in a same chip. |
