This invention relates to a method for extending the range of the input of a pre-differential amplifier. It is composed of: a syntropy input buffer, reverse input buffer, feedforward network, differential output center potential offset circuit, input mode selection. The steps are: the output, from the pre-amplifier and of differential signal input, is proceeded the reversion, after that, forward feeding to a input end of another input buffer amplifier, or the half differential output signal feeding-back to the reverse end of the differential amplifier. This invention method is used for converts single-ended signals into differential signals, particularly, by using delivering feedforward, the bias voltage reverse floating with 1/2 difference mode signal is produced, the center potential of input signal keeps the reference level. And an offset voltage can be added into said reference level, and eliminating effectively common-mode noise, and extending the amplifier input range.
