| Abstract: | Constant-voltage-bridges are widely used in strain gage measuring circuits. Recently, twin-constant-current source has been used abroad in stome instruments. In this paper, the advantages and disadvantages of both circuits and the applications of twin-constant-current source as well as its circuit compensation are discussed. |
