| Abstract: | Inorder to have generalityin scaling operational circuit design.We present an add and subtract operational circuits of arbitrary scaling coefficient.The relationship of the scaling coefficient with balancing resistor and the feedback resistor.The equilibrium conditions of an amplifiers input resistance is converted into the relationship of the scale factor of the input signal.And to explore the input resistance of balance,scale factor value of the relationship between changes in the subtraction circuit constitute a change in the fom.Gives some new circuit designs and expands the application scope of proportional arithmetic circuit. |
