DRIVE CIRCUIT |
| 摘要 |
A drive circuit includes a signal source that outputs an AC signal, a voltage generator circuit that includes a differential amplifier that generates a first AC voltage with a constant amplitude from the AC signal and outputs the first AC voltage to one end of an external load, and a voltage-to-current converter circuit that is connected to another end of the external load and supplies an AC current with a constant amplitude in opposite phase to the first AC voltage to the external load in accordance with the AC signal. |
