摘要:
A reference voltage providing circuit. The operation amplifier includes a non-reverse input terminal, a reverse input terminal and an output terminal coupled to the reverse input terminal for outputting an output voltage. The reference voltage generator is coupled to the non-reverse input terminal. The loading is coupled to the output terminal. The current source provides a starting current. The switching device is coupled between the current source and the output terminal, and turned on by an accelerating charging signal to pass the starting current to the loading through the first output terminal. The pulse output device outputs the accelerating charging signal.
