Novel non-linear macromodel suitable for spice simulation of analogue multipliers realized with bipolar and CMOS technologies

The purpose of this paper is to propose a simple and accurate non-linear ma cromodel for analogue multipliers. The performance of the new macromodel is demonstrated by comparing the SPICE simulation results obtained with the d evice-based models and with the macromodel. The most important result obtai ned in the frame of this work is the combination of accurate modelling with reduced computer time, thus providing the IC designer with the possibility of speeding up the simulation of large electronic systems.
