Abstract
A current generating circuit, which comprises: a first capacitor, comprising a first terminal and a second terminal; a second capacitor, comprising a first terminal and a second terminal; a first charge adjusting path, arranged for adjusting charges of the first capacitor according to a first charge adjusting voltage; a second charge adjusting path, arranged for adjusting charges of the second capacitor according to the first charge adjusting voltage; and a current generating path, coupled to the first capacitor and the second capacitor, arranged for generating a target current based on a difference between a first voltage provided by the first capacitor and a second voltage provided by the second capacitor.
