Patent ID: 7449952

Claim:
An amplifying circuit, comprising: an amplifier, for generating a first pull-up signal, a first pull-down signal according to an input signal received by an input terminal, and for generating an output signal at an output terminal, wherein both the first pull-up signal and the first pull-down signal are inversed signals of the output signal; a pull-up circuit, including: a first controlling module, coupled to the amplifier for receiving the first pull-up signal and for outputting a second pull-up signal according to the first pull-up signal, wherein the first pull-up signal and the second pull-up signal have substantially the same phase; a first adjusting module, coupled to the first controlling module and the output terminal for adjusting the output signal according to the second pull-up signal; a pull-down circuit, including: a second controlling module coupled to the amplifier, for receiving the first pull-down signal and for outputting a second pull-down signal according to the first pull-down signal, wherein the first pull-down signal and the second pull-down signal have substantially the same phase; and a second adjusting module, coupled to the second controlling module and the output terminal, for adjusting the output signal according to the second pull-down signal.
