INTEGRATION CIRCUIT, TOUCH INTERACTION SENSING APPARATUS, AND TOUCHSCREEN APPARATUS |
| 摘要 |
An integration circuit may include a plurality of switches, at least one operational amplifier, and at least one feedback capacitor, sequentially transfers electrical charges charged in a node capacitor to the feedback capacitor, and integrates the electrical charges. The operational amplifier may be synchronized with a clock signal applied to at least one of the plurality of switches to thereby be operated in one of a normal mode and a low power mode. |
