| 摘要 |
The present invention discloses a source driver and a level shifting apparatus thereof. The level shifting apparatus comprises a level shifter and an asynchronous dynamic control circuit. The level shifter has a first switch and connected to a high power supply voltage source via the first switch, wherein the level shifter shifts a level of an input signal and outputs an output signal if enabled. The asynchronous dynamic control circuit sends an enabling signal for temporarily turning on the first switch to enable the level shifter.
