Tunnel diode's volt-ampere characteristics is a N shape curve. The circuit including tunnel diode is the nonlinear circuit. Piece wise liner approximation is a kind of useful method in studying nonlinear circuit. This method divides the characteristics of the nonlinear circuit into several linear sections. Linear circuit's calculating method is used in each sectin. The approach and steps of piece wise linear approximation are introduced in this paper. The method for forming equations after linearization is discussed in detail. In each linear section, a group of linear equations is produced in order to solving the operating point. At last, solve these equations. And their answer is the real operating point of tunnel diode circuit.
