摘要： The present invention relates to a current sensing amplifier and a method thereof. The current sensing amplifier comprises a first current path, a second current path, a first capacitor, a second capacitor and a latch circuit. When a first current and a second current flow in the first current path and the second current path respectively, the first and second capacitor may be charged by the first current and the second current. The first capacitor and the second capacitor may couple the charged voltage to the transistors in the first current path and the second current path when the first and second current path are cut off so as to cancel the effect of offset voltage of the transistors generated during the manufacturing process.
