Abstract
A buffering device includes: a buffering circuit coupled between a first voltage source providing a first voltage level and a second voltage source providing a second voltage level, for selectively outputting an output signal with the first voltage level or the second voltage level according to an input signal; and a controlling circuit coupled to the buffering circuit, for generating a first control signal to disconnect the buffering circuit from the first voltage source and generating a second control signal to connect the buffering circuit to the second voltage source when the buffering circuit transits the output signal from the first voltage level to the second voltage level. The second voltage level is different from the first voltage level.
