Abstract :
A software package is presented that generates symbolic or numerical results for gain, noise, and distortion behavior of weakly nonlinear analog integrated circuits with multiple inputs. The program provides insight into the behavior of mixers, multipliers, and AGC amplifiers. This analysis tool is part of the symbolic simulator ISAAC, and it can reduce the design time of the above-mentioned circuits by giving insight into conversion gain, intermodulation distortion, and noise that mixes with signals. Analytic expressions make it possible to identify the dominant parameters that determine the circuit´s nonlinear behavior
