Abstract
An embodiment of the present invention discloses a voltage amplifier circuit which includes a signal generator, a mixer and an amplifier. The signal generator is arranged to generate an input signal; the mixer is arranged to mix the input signal with an analog signal to generate an intermediate input signal having a first voltage range; and the amplifier is arranged to convert the intermediate input signal into an output signal having a second voltage range in a Rail-to-Rail manner, wherein the second voltage range is larger than the first voltage range.
