Calculation method is usually used for nonlinear circuit analysis. It is difficult to obtain analytic solution. Based on the inverse operator method（IOM） for one-order nonlinear circuit analysis ,this paper gives light on the approximate analytical solutions of response. It is indicated that the analysis process is simple, and there is same relation of calculation between solution components, so solution components can be calculated easily with computer. IOM is an effective method of analysis of nonlinear circuit.
