| Abstract(in English) | Distortion analysis of nonlinear circuits is very important for designing analog integrated circuits and/or communication systems. Although the Volterra series methods have been widely used for these purposes, they can be only applied to weakly nonlinear systems, where nonlinear elements should be described by power series. In this paper, we propose a harmonic balance method for solving the frequency response curves. It is known that the determining equation are described by the analytical functions only when the nonlinear elements are described by the polynomial functions. Unfortunately, many nonlinear devices of the electronic circuit are modeled by using many special functions and piecewise continuous functions. Therefore, we need to develop a Fourier transformer using ABMs of Spice which carries out the Fourier transformation of any kind of nonlinear devices. Using the transformer, we firstly construct the equivalent modules of MOSFETs. Combining these modules, we can formulate the determining equations of the harmonic balance method which is given in the forms of the resistive circuits, so that it can be solved by the DC analysis of Spice. We apply the technique to CMOS differential amplifiers. |
