Abstract

In this work the modified Gummel Poon model (MGPM), implemented in the SPICE 3F4 simulator, is used to predict the effects of an RF disturbance in bipolar circuits. In fact in the presence of the conducted RF disturbances, the monodimensional models currently used for circuit simulations (Ebers Moll, Gummel Poon), cannot provide the behaviour of the device with sufficient accuracy. In particular, the modified SPICE 3F4 simulator has been used to predict BJT circuit susceptibility, performing .OP, .DC, .AC and .TRAN analysis, for the following interference signals: continuous wave (CW), amplitude modulated (AM) or frequency modulated (FM) disturbances, with carrier frequency in the range 100 MHz-1 GHz and RF power level up to 0 dBm
