ABSTRACT:
A voltage conversion device having non-linear gain and changeable gain polarity includes a switch module, a gain decision module, a first voltage selection module, a second voltage selection module, a first switch unit, a second switch unit and a voltage output module. The switch module is used for outputting analog voltage provided by the analog voltage source or voltage corresponding to the system ground end. The gain decision module is used for determining a gain. The first voltage selection module is used for outputting a first DC voltage. The second voltage selection module is used for outputting a second DC voltage. The first switch unit is used for outputting the first DC voltage. The second switch unit is used for outputting the second DC voltage. The voltage output module is used for outputting an amplified result of a DC voltage according to the gain.
