DETECTION CIRCUIT, SENSOR DEVICE AND ELECTRONIC APPARATUS |
| 摘要 |
A detection circuit includes a pyroelectric element, an amplifier circuit, a first switching element and a second switching element. The amplifier circuit includes a transistor in which a detection signal from the pyroelectric element is inputted to a gate. The first switching element interrupts an electric current that flows into the transistor. The second switching element interrupts a connection between the pyroelectric element and the gate of the transistor. |
